Revisiting Arveson’s Dirac operator of a commuting tuple

4:00PM, Wed Oct 16 2019, Room 250 Mathematics Bldg

About twenty years ago, Arveson introduced an abstract Dirac operator based on Taylor spectrum and functional calculus. He showed that every Dirac operator is associated with a commuting tuple. The Dirac operator of a commuting tuple has inspired several interesting problems in multivariable operator theory. In this talk, we will revisit the Dirac operator and discuss some related problems.

A Quant’s Journey Toward Diversification

4:00PM, Thu Oct 17 2019

Portfolio diversification is a useful technique that has the potential to improve risk-adjusted returns for an investment portfolio. In this presentation we take a detailed look at diversification through theoretical considerations as well as empirical results. We analyze the degree of potential benefit of diversification as well as its limitations and trade-offs. This provides a glimpse into quantitative research conducted by Graham Capital’s systematic investment team.

Masser’s conjecture on equivalence of integral quadratic forms

4:00PM, Wed Oct 23 2019

A classical problem in the theory of quadratic forms is to decide whether two given integral quadratic forms are equivalent. Formulated in terms of matrices the problem asks, for given symmetric n-by-n integral matrices A and B, whether there is a unimodular integral matrix X satisfying A=X’BX, where X’ is the transpose of X. For definite forms one can construct a simple decision procedure. Somewhat surprisingly, no such procedure was known for indefinite forms until the work of C. L. Siegel in the early 1970s. In the late 1990s D. W. Masser conjectured for n at least 3, there exists a polynomial search bound for X in terms of the heights of A and B. In this talk we shall discuss our recent resolution of this problem based on a joint work with Professor Gregory A. Margulis, and explain how ergodic theory is used to understand integral quadratic forms.

- Welcome new faculty9/5/19
The Department of Mathematics is pleased to welcome new faculty starting Fall 2019:

**-Naoki Masuda,**Associate Professor (Applied Mathematics);

**-Simone Cassani**, Visiting Assistant Professor (Applied Mathematics);

**-Xin Ma,**Visiting

-**Margaret Nichols,**Visiting Assistant Professor (Geometric Topology);

**-Michael A. Rosas,**Clinical Assistant Professor, Calculus Coordinator (Representation Theory, Mathematics Education) - 8/16/19New research from the University of Buffalo, using computational models of individual people’s connectomes, shed light into individual differences in brain activation patterns, as well as how those patterns may change over time. Since 2009, scientists around the globe have worked to create the Human Connectome, a structural blueprint of the various neural pathways and connections that underlie thought, reason, emotion, and behavior in the brain. Thanks to those pioneering efforts, we now understand that different regions of the brain work together in concert, forming specific networks that facilitate movement, or learning, or our interactions with others—the cognitive skills that allow us to survive and thrive in our daily lives. Yet despite these advances, it’s still not entirely clear how these networks may differ from person to person. Sarah Muldoon, a mathematician at the University of Buffalo, has long been interested in understanding individual differences in the brain.
- 4/30/19Congratulations to Mark Marino on winning the 2018-2019 Milton Plesur Award for Excellence in Teaching. This award is given by the UB Student Association on behalf of the students who nominate their instructors. The award carries the honor of being recognized as an outstanding professor by the students they teach. Marino was presented the award at the organization's annual event, April 29, 2019.

Mousa Sunnoqrot is a senior at the State University of New York at Buffalo in Amherst, New York, where he is majoring in Mathematics and minoring in Economics and Statistics, with a concentration on Actuarial Science. Mousa is the professional chair for University at Buffalo’s student-run Society of Future Actuaries, and he interned this past summer at Healthfirst in New York City. Mousa is featured in a Q&A by AdvisorSmith, a provider of comprehensive research and advanced tools to better understand insurance for business professionals.

- 5/3/19The University at Buffalo Department of Mathematics is pleased to announce that Destiny Diaz has won the National Science Foundation’s Graduate Research Fellowship Award. The prestigious award is one of the most competitive and respected scientific fellowships in the U.S. Diaz is completing a BS in mathematics with a minor in Spanish. Recently, Diaz received 2019 SUNY Chancellor’s Award for Student Excellence. A Buffalo native, she is a member of the University Honors College and a Prosperity Fellow. In Fall 2019, the NSF Graduate Research Fellowship will support her pursuit of graduate study in biostatistics at UB. The award provides three years of financial support within a five-year fellowship period, which amounts to a $34,000 annual stipend and $12,000 cost-of-education allowance to the graduate institution.
- 4/23/19Congratulations to the UB Student Team upon achieving the designation of Meritorious Winner in the 2019 Mathematical Contest in Modeling.

- 7/15/16Each summer, the “Summer Math Scholarship” is awarded to one UB Mathematics major. The scholarship allows the recipient to pursue individual research with a faculty mentor. The six-week, full-time, summer program provides a stipend of $3,000. The following academic year the research will be writtenup into a senior honors thesis. Applications are due each Fall. To apply for the scholarship, consult with your faculty mentor.
- 2/22/19Matthew Eichhorn, a junior from Williamsville, NY, who is double majoring in Mathematics and Computer Science, has won our second Math Summer Scholarship. Matt is highly involved in the Math Department, participating in competitions including the Putnam exam and the Rochester Math Olympiad. Additionally, he has served as an undergraduate teaching assistant for both MTH 141 and MTH 241, as well as a tutor in the Thomas J. Edwards Undergraduate Learning Center, which assists students with material ranging from algebra and trigonometry through MTH 142.

The scholarship provides the opportunity for Matt to study theory and applications of machine learning under the guidance of Dr. John Ringland. The primary application will be designing and using deep convolutional neural networks to analyze Google Street View imagery from rural Thailand, with the ultimate goal of determining how farming practices, especially small-scale residential horticulture, are related to the food-security and health of the population. - 12/5/17Founded by UB students interested in actuarial careers, "The Society of Future Actuaries" (SOFA) is now a club with roughly half of the membership interested in general data analytics.
