Dr Willy Hereman, Colorado School of Mines
Symbolic computation of solitary wavesolutions and solitons through homogenization of degree
4:00PM, Mathematics Building room 250

A simplified version of Hirota's method for thecomputation of solitary waves and solitons of nonlinear PDEs will be presented.The approach requires a change of dependent variable so that the transformedPDE is homogenous of degree in the new variable.

The resulting homogenous PDE does not have tobe quadratic and the method still applies if its bilinear form is not known.Solitons are then computed using a perturbation scheme involving linear andnonlinear operators. For soliton equations the scheme terminates after a finitenumber of steps. To illustrate the approach, solitons are computed for a classof fifth-order KdV equations due to Lax, Sawada-Kotera, and Kaup-Kupershmidt.

Homogenization of degree also allows one tofind solitary wave solutions of nonlinear PDEs that are not completelyintegrable. Examples include the Fisher and FitzHugh-Nagumo equations, and acombined KdV-Burgers equation. When applied to a wave equation with a cubicsource term, the method leads to a `bi-soliton' solution which describes thecoalescence of two wavefronts.

The method is largely algorithmic andimplemented in Mathematica. A demonstration of the software packagePDESolitonsSolutions will be given.

UB Math Spotlight

  • PNAS publishes collaborative research that sheds light on steep ocean wave dynamics
    In a new collaborative study published in the Proceedings of the National Academy of Sciences (PNAS), a team of researchers from the University of Washington, SUNY at Buffalo and the University of New Mexico have unveiled the dominant mechanism behind wave-breaking of tall oceanic waves. The research team includes Prof. Bernard Deconinck (UW), Prof. Sergey Dyachenko (UB), Prof. Pavel Lushnikov (UNM) and Dr. Anastassiya Semenova (UW).
  • Linda Alegria, UB Math Graduate Student, wins Excellence in Teaching Award
    The Department of Mathematics is pleased to announce that Linda Alegria has been awarded the University at Buffalo's 2022 Excellence in Teaching Award for Graduate Student Teaching Assistants. The award was presented at a luncheon in April, with Satish Tripathi, UB President, and Robin Schulze, CAS Dean, in attendance.
  • Julia Shapiro wins SUNY Chancellor's Award for Student Excellence
    The University at Buffalo Department of Mathematics is pleased to announce that Julia Shapiro, winner of the 2022 SUNY Chancellor's Award for Student Excellence. Shapiro will graduate with a bachelor of science in mathematics, and her accomplishments as an undergraduate student include: University Honors College Scholar,  winner of the 2021 Harriet F. Montague Award, and President of the UB Undergraduate Math Club. Shapiro has completed research on Markov Chains through a nationally recognized program at the University of Connecticut, has been a Peer Mentor in the Honors College,  has served as an Ambassador of both the Honors College and the College of Arts and Sciences, and has served as an Undergraduate Teaching Assistant in three separate departments — Mathematics, Biostatistics, and Computer Science. 
  • Professor Sarah Muldoon delivers session on analyzing neuroimaging data across scales
    Statisticians from across upstate New York will descend on UB May 2-4 for UP-STAT 2022, the 10th joint conference of the Upstate Chapters of the American Statistical Association. Sarah Muldoon, associate professor in the Department of Mathematics, UB College of Arts and Sciences, will deliver a special invited session on modeling and analyzing neuroimaging data across scales.

  • Professor Hanfeng Li named to AMS 2021 Class of Fellows
    The University at Buffalo Department of Mathematics is pleased to announce that the American Mathematical Society has named Professor Hangfeng Li a member of the 2021 Class of Fellows. The international honor places Professor Li among the world's outstanding mathematicians for his contributions to algebraic dynamics and operator algebras. He joined UB Mathematics in 2005, and is currently teaching MTH 424/524, “Survey of Fourier Series Methods”. His main research interest is on noncommutative geometry and dynamical systems, especially connections between operator algebras and dynamical systems. Professor Li's recent work concentrates on actions of countable sofic groups and algebraic actions of general countable (amenable) groups. Read the article by Charlotte Hsu.
  • Giacomo Scilla wins the 2023 Summer Math Scholarship
    The UB Department of Mathematics is pleased to announce that Giacomo Scilla is the recipient of the 2023 Summer Math Scholarship. Together with faculty mentor Dr. Gino Biondini, Scilla formulated an undergraduate research project aimed at understanding the classification of two-dimensional wave patterns governed by the solutions of the Kadomtsev-Petviashvili equation, with the ultimate goal of deriving efficient methods to generate large ensembles of such solutions.
  • Robert Busch wins Milton Plesur Excellence in Teaching Award
    The Department of Mathematics is pleased to announce that Robert Busch, clinical assistant professor, is the winner of the coveted Milton Plesur Excellence in Teaching Award, 2019-2020. Busch was recognized by the undergraduate Student Association for his commitment and dedication to students. He was nominated for the award by his students. Upon news of the award, Busch's first thought was to acknowledge his students: “To all my students, over all the years, and in all the classes…for giving me the privilege of being your instructor, for making me into a better teacher, communicator, and human being, for the pleasure of watching you learn and succeed, and for the thrill of seeing you graduate and step into your dreams…from the bottom of my heart…THANK YOU.”
  • Professor Naoki Masuda wins JSPS Prize
    The University at Buffalo Department of Mathematics is pleased to announce that Dr. Naoki Masuda, Associate Professor, is the winner of the JSPS (Japan Society for Promotion of Science) Prize 2020. The national award recognizes his work, “Pioneering Research on Theory and Data-Analysis Methods for Temporal Networks”. Dr. Masuda attended the JSPS Awards Ceremony in February, 2020, accompanied by his daughter, Ami Masuda. The JSPS 2020 Award included full funding of their travel to Japan. While there, Dr. Masuda and Ami participated in an exclusive audience with the Japanese Royal Family.
  • Destiny Diaz wins NSF Graduate Research Fellowship Award
    The 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.
  • UB Math Grads win NSF Graduate Research Fellowships
    The National Science Foundation Graduate Research Fellowship Program (GRFP) named a record number of winners from UB this year, one more than all the awards given to students in the rest of the SUNY system. For the 2016 competition, NSF received close to 17,000 applications, and made 2,000 award offers.
