2015, 2016, 2017: Listing of hosted events forthcoming.

Two teams of undergraduates participated in the 2014 Mathematical Contest in Modeling. The team of Andrew Harris, Dante Iozzo, and Nigel Michki was designated as "Meritorious Winner" (top 9%) and the team of George Braun, Collin Olander, and Jonathan Tang received honorable mention (top 31%). John Ringland served as the faculty advisor to both teams.

The Mathematical Contest in Modeling is a multi-day mathematics competition. It is distinguished from other major mathematical competitions such as Putnam by its strong focus on research, originality, teamwork, communication and justification of results. This year there were 6,755 teams participating from around the world. [April 2014]

Stephen H. Schanuel passed away July 21, 2014 just a few days after his 81st birthday on Bastille Day. He leaves his son Jason, daughter Lynn (Carlos), grand daughter Jenna, and a sister.

Steve came from modest beginnings in St. Louis where his mother struggled to care for Steve and his, his three sisters and a brother. Steve’s father was a traveling salesman. Even though he won free tuition to Princeton, he worked long hours in a cafeteria where he got free food. One of his professors (I forget who) impressed with his ability, discovered Steve's circumstances, was concerned he did not have enough time to do mathematics, and subsequently obtained a scholarship to support Schanuel's room and board.

Steve began graduate school in Mathematics at The University of Chicago where we worked with Irving Kaplansky. He earned his PhD from Columbia in 1963 under Serge Lang. Before joining UB in 1972, he was at Johns Hopkins, Cornell, and SUNY Stony Brook. Though Steve came here as a heralded young Number Theorist, his contributions to Algebra were nearly as notable. Schanuel’s Lemma in Homological Algebra was publicized by Kaplansky when Steve was a student. In Number Theory, the Schanuel Conjecture, also discovered when he was a student, is a famous still open problem (for a brief statement see my article "Million-Buck Problems" in The Mathematical Intelligencer (2002), for an early study see James Ax’s article "On Schanuel’s Conjectures," Annals of Mathematics 1971.)

Steve’s interests were very wide, so wide that many of our colleagues outside Algebra and Number Theory would talk with him. Steve has written with several of our colleagues; however, he was a long time collaborator with our colleague F. William (Bill) Lawvere, with whom he wrote papers and published a popular book "Conceptual Mathematics." A second book, "Objective Number Theory" is forthcoming.

From 1986 until 1998, Steve was a member of the Friday after school "Sign of the Steer" (on Main street) beer group whose nucleus was Don Schack, Mohan Ramachandran, Jim Reineck, Bill Lawvere and Scott Williams. From 1998 to 2010 that group became the coffee group at Wegmans and the "Coffee Bean Cafe" now renamed the restaurant "Shango" on Main Street where much mathematics (Number Theory, Measure Theory, Category Theory, Topology, Set Theory), and politics, music, art and psychology was discussed six or seven days a week. We met nearly every Saturday morning and once a month on Sunday morning.

I have many fond personal memories of Steve, beginning with discussing poetry with his wife Joan and he during the 1970s. Steve was quite humble. People were often surprised with what he knew. If someone's wife or child were present, he would show interest and listen to them. He was a span, enjoying football, tennis, and track & field.

Once, when Steve visited my home in the 1980s, he brought his guitar. After dinner he complained that he did not know how to improvise on the instrument. Though I could not play the guitar, I played the piano. At our piano I improvised three pieces by respectively George Gershwin, Miles Davis and Rogers & Hammerstein. Steve said, "like that?" and then proceeded to improvise on the piano so much better than I that I never again played in front of him. Yes it was the guitar, not the piano, that caused his problem. In the 1990s Steve introduced me to the poet Billy Collins. A few years later, I owned five Collins poetry books. My most striking mathematical memory was during the 11 weeks in 2005 when I was hospitalized. Steve and Don Schack visited me daily for hours, where we read and tried to work out all the known solutions of Hilbert’s problems.

Steve retired in 2011 and left Buffalo a year later to be near his daughter Lynn and family in Florida.

I received the following note from Jill Paolini who studied with Steve and I:

"That makes me so sad. I loved him. I wrote a poem, "Ode to My Math Teacher," about him. and bought "Conceptual Mathematics" for myself for my birthday. We used to call him 'Schanuel the Manual' because he needed and used no book. He had a glint in his eye, like Santa, even if he shaved his white beard in December. I am so sorry to hear he passed. I will nurture what he taught me, and remember him with a smile on my face, even though right now I am looking through a layer of water. I remember one day in class... I asked a question and Professor Schanuel said, "That's a great question. Does anyone mind if I discuss this instead of what I was going to talk about? This is far more interesting." I also remember clearly our final exam for a 400/500 level algebra course. He gave us each 8 pieces of blank paper and told us to show him we had learned something. He said we could prove our favorite theorem, or solve a problem we could not have solved prior to his course. He concluded by telling us that he needed some encouragement, and asked us to please show him that we had learned something. Vu To was sitting next to me. He was about 18 years old, a math Olympian from Vietnam. I remember he looked so surprised and wrote nothing for at least 15 minutes... and then proceeded to write with confidence and probably encouraged Professor Schanuel with a beautiful treatise. Another story comes to mind... and another…"

In 1798, there appeared in the "Philosophical Transactions of the Royal Society" a paper by James Wood, purporting to prove the fundamental theorem of algebra, to the effect that every non-constant polynomial with real coefficients has at least one real or complex zero. Since the first generally accepted proof of this result was given by Gauss in 1799, Wood's proof deserves careful examination.

Congratulations to Emeritus Professor F. William Lawvere on being named a Fellow of the American Mathematical Society. Professor Lawvere is a member of the highly-distinguished inaugural class of Fellows. A full listing of AMS Fellows is at http://www.ams.org/profession/fellows-list-institution. [November 2012]

The Mathematics Department congratulates all of our graduating seniors. We also congratulate the following award winners: James Kotary (2012 Gehman Scholarship), David Trabucco (2012-13 Hazel and John Wilson Undergraduate Mathematics Scholarship), and John Susice (2012 Oustanding Senior and Harriet F. Montague Award).

Professor Mladen Bestvina from the University of Utah presented the Myhill Lecture Series for 2012. This 3-part lecture series was held Tue Apr 17 - Thu Apr 19, and included a reception in honor of Professor Besvina immediately following the first lecture. See the Mathematics Department Calendar for more information.

Congratulations to Alyssa Brown, graduate student in Mathematics, who will be receiving an Honorable Mention in this year's Graduate Student Excellence in Teaching Awards competition. The Graduate School and the Graduate Student Association established the Graduate Student Excellence in Teaching Awards Program to publicly recognize those graduate students who have demonstrated exceptional performance in the execution of their teaching responsibilities.

Please join us in congratulating Professor John Ringland who is this year's winner of the 2012 Clarence F. Stephens Distinguished Teaching Award from the Mathematical Society of America Seaway Section. In 1991, the Board of Governors of the MAA established the Section Awards for distinguished College or University Teaching of Mathematics to recognize teachers of Mathematics at the post-secondary level who have been widely recognized as extraordinarily successful. Their teaching effectiveness must be documented and must have had influence beyond their own institutions. As sectional winner, Professor Ringland will be automatically nominated for the national MAA Haimo Award. Congratulations!

The department welcomes its new Chair, David Hemmer. Professor Hemmer is taking over from Brian Hassard, who served two three-year terms as Chair. At the same time, Bernard Badzioch will take over the duties of Director of Undergraduate Studies, replacing David Hemmer who served in that position for three years. The department particularly thanks Brian Hassard for his 6 years of dedicated service to the department in capacity of Chair, and extends its gratitude to Professors Hemmer, Faran, Biondini and Badzioch who will be serving the department in administrative roles.

Two Math Dept faculty members have recently had books published. Prof. Jonathan Dimock's is "Quantum Mechanics and Quantum Field Theory: A Mathematical Primer", published by Cambridge University Press. Prof. Mohan Ramachandran's is "An Introduction to Riemann Surfaces", published by Birkhauser.

Tuesday, December 20, 2011

13 undergraduate math majors in the 2009 cohort of the URGE to Compute program traveled to the AMS/MAA Joint Meetings in San Francisco, CA, January 14-17 2010, to give talks on their research results. The students were accompanied by their research mentors, Profs. John Ringland and Gino Biondini of the UB Math Department and Prof. Saziye Bayram of the Buffalo State College Math Department.

URGE to Compute provides apprenticeships worth $10,000 to each of 12 students annually to conduct research of a computational nature in mathematics and the mathematical sciences. URGE stands for Undergraduate Research Group Experiences, and it is the implementation in Buffalo of the National Science Foundation's CSUMS program. It is a collaboration of the UB and Buffalo State Mathematics Departments, the UB Physics Department, the UB Center for Computational Research, and the Hauptman Woodward Medical Research Institute. Students accepted to the program will conduct a year-long program of research, closely mentored by faculty, and engage in many activities that support the research and their intellectual and personal development.
