### Seminars for Pure Mathematics

 Apr 27 Paige North (University of Pennsylvania) TBA Homotopy Theory Seminar Time: 5pm Location: Zoom Apr 13 Maximilien Péroux (University of Pennsylvania) Coalgebras and comodules in stable homotopy theory. Homotopy Theory Seminar Time: 5pm Location: Zoom In higher algebra, we study algebraic objects endowed with a multiplication that is associative only up to (coherent) homotopy, or commutative up to (coherent) homotopy. In this Brave new algebra, we ... More Apr 8 Melissa Emory (University of Toronto) TBA Algebra and Its Applications Time: 3:05 Location: Zoom Apr 6 Alexander Campbell (Centre of Australian Category Theory, Macquarie University) A model-independent construction of the Gray monoidal structure for (infinity,2)-categories Homotopy Theory Seminar Time: 6pm Location: Zoom In this talk I will describe joint work with Yuki Maehara in which we give a model-independent (i.e. a purely infinity-categorical) construction of the (non-symmetric) Gray monoidal structure on the i... More Apr 1 Joe Webster (University of Oregon) The p-adic Mehta Integral Algebra and Its Applications Time: 3:05 Location: Zoom Mar 25 Raghuram (IISER Pune) An introduction to Eisenstein Cohomology and its arithmetic applications Algebra and Its Applications Time: 9:45AM Location: Zoom Mar 23 Martina Rovelli (University of Massachusetts Amherst) n-complicial sets as a model for (infinity, n)-categories Homotopy Theory Seminar Time: 5 pm Location: Zoom With the rising significance of (infinity, n)-categories, it is important to have easy-to-handle models for those and understand them as much as possible. In this introductory talk we will discuss how... More Mar 18 Kaneenika Sinha (IISER Pune) Central limit theorems for Sato-Tate sequences Algebra and Its Applications Time: 9:45AM Location: Zoom Mar 11 Adriana Salerno (Bates College) Hasse-Witt matrices and mirror toric pencils Algebra and Its Applications Time: 3:05 Location: Zoom Mirror symmetry predicts unexpected relationships between arithmetic properties of distinct families of algebraic varieties. For example, Wan and others have shown that for some mirror pairs, the numb... More Mar 4 Kate Petersen (FSU) Average Height Bounds Algebra and Its Applications Time: 3:05 Location: Zoom Feb 25 Melissa Emory (University of Toronto) A multiplicity one theorem for general spin groups Algebra and Its Applications Time: 3:05 Location: Zoom Feb 11 Ettore Aldrovandi (FSU) Fiber integration in K-Theory and a construction of Deligne's Algebra and Its Applications Time: 3:05 Location: Zoom Feb 9 Rhiannon Griffiths (Case Western Reserve University) Enriched Model Categories for Functor Calculus Homotopy Theory Seminar Time: 5 pm Location: Zoom We present results necessary for developing model categories of enriched functors suitable for doing functor calculus. As a first example, we show how the discrete functor calculus of Bauer, Johnson a... More Feb 4 Mark van Hoeij (FSU) Modular GCD Algorithm Algebra and Its Applications Time: 3:05 Location: Zoom Jan 28 Alia Hamieh (UNBC) Mean Values of Long Dirichlet Polynomials with Higher Divisor Coefficients Algebra and Its Applications Time: 3:05 Location: Zoom Jan 19 Christina Osborne (Cedarville University) Decomposing the classifying diagram in terms of classifying spaces of groups Homotopy Theory Seminar Time: 5 pm Location: Zoom The classifying diagram was defined by Rezk and is a generalization of the nerve of a category; in contrast to the nerve, the classifying diagram of two categories is equivalent if and only if the cat...
