THU, OCT 26 Colloquium Lei Yang, Institute for Advanced Study Effective versions of Ratner’s equidistribution theorem 4:00PM, Mathematics Building, room 250 I will talk about recent progress in the study of quantitative equidistribution of unipotent orbits in homogeneous spaces, namely, effective versions of Ratner's equidistribution theorem. In particular, I will explain the proof of unipotent orbits in SL(3, R)/SL(3, Z). The proof combines new ideas from harmonic analysis and incidence geometry. In particular, the quantitative behavior of unipotent orbits is closely related to a Kakeya model. MON, OCT 30 Algebra Seminar Bach Nguyen, Xavier University : Poisson geometry and the representation theory of cluster algebras Abstrract: The relationship between Poisson geometry and cluster algebras was first studied by M. Gekhtman, M. Shapiro, and A.Vainshtein. Following their work, we study the global geometry picture of the affine Poisson varieties associated with a cluster algebra and its quantizations, root-of-unity quantum cluster algebras. In particular, we prove that the spectrum of the upper cluster algebra, endowed with the GSV Poisson structure, has a Zariski-open orbit of symplectic leaves and give an explicit description of it. Our result provides a generalization of the Richardson divisor of Schubert cells in flag varieties. Further, we describe the fully-Azumaya loci of the root-of-unity upper quantum cluster algebras, using the theory of Poisson orders. This classifies their irreducible representations of maximal dimension. This is joint work with Greg Muller, Kurt Trampel and Milen Yakimov. 4:00PM, Mathematics Building room 250 SPEAKER: Bach Nguyen, Xavier University Title:: Poisson geometry and the representation theory of cluster algebras Abstrract: The relationship between Poisson geometry and cluster algebras was first studied by M.

WED, NOV 1 Analysis Seminar Jinmin Wang, Texas A&M University Stoker's problem and index theory on manifolds with polytope singularities 4:00PM, 250 Math Building The Stoker problem states that the dihedral angles of a convex Euclidean polyhedron determine the angles of each faces. In this talk, I will present joint works with Zhizhang Xie and Guoliang Yu that answer positively to Stoker's problem, and prove a more general dihedral rigidity for manifolds with polytope singularities. I will briefly introduce our approach, the index theory of Dirac-type operators on manifolds with polytope singularities under certain boundary conditions. One of the key observations is the essential self-adjointness of the Dirac-type operators near conical singularities.

FRI, NOV 10 Applied Math Seminar Dmitry Pelinovsky, Mcmaster University Instability of peaked waves in hydrodynamical models. 3:00PM, Math 122 and on Zoom - contact mbichuch@buffalo.edu for link Stokes' wave is a traveling (periodic or solitary) wave with a stagnation point at its crest, where the surface of fluids has a peaked singularity. Stokes waves have been considered within Euler's equations and have been modeled by using reduced equations of motion such as the Camassa-Holm equation, the rotation-modified Ostrovsky equation, and other systems with wave breaking. I will overview the recent analysis of nonlinear, linear, and spectral instability of the traveling peaked waves in some reduced models such as the b-family of the Camassa-Holm equations. Well-posedness of the initial-value problem for this family holds in the energy space as long as the first spatial derivative (the wave slope) is bounded. We show that the travelling peaked waves are unstable due to wave breaking when the wave slope becomes unbounded in a finite time. This instability can also be studied by using the spectral stability analysis within the linearized equations of motion obtained consistently with the well-posedness results. FRI, NOV 17 Applied Math Seminar Giselle Sosa Jones, Oakland University Discontinuous Galerkin discretizations of multiphase flow problems in porous media. 3:00PM, Math 122 and on Zoom - contact mbichuch@buffalo.edu for link Modeling the flow of liquid, aqueous, and vapor phases through porous media is a complex and challenging task that requires solving nonlinear coupled partial differential equations. In this talk, we propose a second-order accurate and energy-stable time discretization method for the three-phase flow problem in porous media. We prove the convergence of the subiterations to resolve the nonlinearity, and show that the time-stepping method mimics the energy balance relation that the continuous problem satisfies. Our spatial discretization uses an interior penalty discontinuous Galerkin method, for which we establish the well-posedness of the discrete problem and provide error estimates under certain conditions on the data. We validate our method through numerical simulations, which show that our approach achieves the expected theoretical convergence rates. Furthermore, the numerical examples highlight the advantages of our time discretization over other time discretizations.

FACULTY SPOTLIGHT previous next * PNAS publishes collaborative research that sheds light on steep ocean wave dynamics 11/3/20 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). * Dana Foundation News: Muldoon’s research probes questions about individual differences in brain activity 8/22/20 New 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. * Professor Hanfeng Li named to AMS 2021 Class of Fellows 11/3/20 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.
