Perverse filtrations via Brylinski-Radontransformations Abstract : Perverse sheaves are certain complexes ofconstructible sheaves invented by Goresky-MacPherson in 1983. This talk will becentered around the topic of (middle) perverse sheaves and more generally ont-structure(s) on the derived category of constructible sheaves on an algebraicvariety \(X\) defined over a field \(\Bbbk\). A t-structure gives rise to truncation functors and hence a cohomologytheory which takes values in the abelian category of perverse sheaves. Acomplex \(K\) of constructible sheaves on \(X\) can be filtered using thesetruncation functors, in turn inducing a filtration on the (hyper)cohomology ofthe complex \(K\). In 2010, deCataldo-Migliorini proved a result which explainsthis filtration geometrically. In recent work with K. V.

Abstract : Perverse sheaves are certain complexes ofconstructible sheaves invented by Goresky-MacPherson in 1983. This talk will becentered around the topic of (middle) perverse sheaves and more generally ont-structure(s) on the derived category of constructible sheaves on an algebraicvariety \(X\) defined over a field \(\Bbbk\). A t-structure gives rise to truncation functors and hence a cohomologytheory which takes values in the abelian category of perverse sheaves. Acomplex \(K\) of constructible sheaves on \(X\) can be filtered using thesetruncation functors, in turn inducing a filtration on the (hyper)cohomology ofthe complex \(K\). In 2010, deCataldo-Migliorini proved a result which explainsthis filtration geometrically. In recent work with K. V.

  • Badzioch wins SUNY Chancellor’s Award for Excellence in Teaching
    10/2/24
    Bernard Badzioch has won the 2024 SUNY Chancellor’s Award for Excellence in Teaching. The award will be presented October 24, 2024 at UB's Celebration of Academic Excellence.  Badzioch is recognized for consistently demonstrating superior teaching at the undergraduate and graduate level. As an innovative educator, students remark that Badzioch has the “rare skill, particularly amongst mathematicians,” to understand even their most incomprehensible questions and answer in a way that makes them feel good for having asked it. Read UBNow.
  • Barbara Prinari, co-founder and deputy editor, Cambridge Journal of Nonlinear Waves
    9/9/24
    The UB Department of Mathematics is pleased to announce that Professor Barbara Prinari is co-founder and deputy editor of Cambridge Core's Journal of Nonlinear Waves. Prinari's research adds scope and depth to the journal's editorial board. Problems addressed by Prinari include the development of the Inverse Scattering Transform (IST) as a tool to solve the initial-value problem for scalar, vector and matrix continuous and discrete nonlinear Schrodinger (NLS) equations with both vanishing and nonvanishing boundary conditions at infinity; solitons and rogue wave solutions; vector soliton interactions, etc.  
  • Hanfeng Li named UB Distinguished Professor
    11/3/20
    Hanfeng Li has been named UB Distinguished Professor. His primary research interest is noncommutative geometry and dynamical systems, particularly connections between operator algebras and dynamical systems. A 2020 fellow of the American Mathematical Society (AMS), his recent work concentrates on actions of countable sofic groups and algebraic actions of general countable (amenable) groups. 
  • The power of stochastic differential equations
    5/8/24
    A new algorithm developed by Naoki Masuda, with co-athors Kazuyuki Aihara and Neil G. MacLaren, can identify the most predictive data points that a tipping point is near. Published in Nature Communications, this theoretical framework uses the power of stochastic differential equations to observe the fluctuation of data points, or nodes, and then determine which should be used to calculate an early warning signal. The algorithm is unique in that it fully incorporates network science into the process.
  • 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).
