Algebra and Combinatorics Seminar: Jacob Matherne, NC State
SAS 4201Speaker’s webpage: https://math.sciences.ncsu.edu/people/jpmather/
Teaching and Learning Seminar: Sunghwan Byun, NCSU College of Education, : Knowledge in Interaction: A Key to Promote Participatory Equity During Whole-Group Discussions
SAS 4201Research shows inequitable participation patterns are pervasive in mathematics classrooms. Thus, an important consideration for mathematics instructors is promoting participation by students with historically marginalized backgrounds. Existing literature often focuses…
Geometry and Topology Seminar: Keaton Naff, MIT, The prescribed-point area estimates in space forms
SAS 1216We discuss a sharp area estimate for minimal submanifolds that pass through a prescribed point in a geodesic ball in a space form. The estimate in Euclidean space was first conjectured by…
Colloquium: Eitan Tadmor, University of Maryland, Swarm-Based Random Descent Method for Non-Convex Optimization
SAS 4201We introduce a Swarm-Based Random Descent (SBRD) method for non-convex optimization. The swarm consists of agents, identified with positions, x, and masses, m. There are three key aspects to the…
Algebra and Combinatorics Seminar: Nathan Reading, NC State, Posets for cluster variables in cluster algebras from surfaces
SAS 4201This talk will introduce cluster algebras, with an emphasis on their combinatorics, and describe a recent joint result with Vincent Pilaud and Sibylle Schroll. At the heart of a cluster…
Nonlinear Analysis Seminar and Differential Equation Seminar: Liviu Ignat, Institute of Mathematics, Simion Stoilow of the Romanian Academy, Romania, Asymptotic behavior of solutions for some diffusion problems on metric graphs
ZoomIn this talk we present some recent result about the long time behavior of the solutions for some diffusion processes on a metric graph. We study evolution problems on a…
Biomathematics Seminar: Xingcheng Lin, Genome Organization from the Ground Up – Deciphering Molecular Mechanisms for Chromatin Organization
Cox 306Chromatin structure tightly regulates gene expression and epigenetic processes. The nuclear environment is complex, featuring tension exerted by force-generating proteins and molecular crowding modulated by different ionic concentrations. Understanding the…
Computational and Applied Mathematics Seminar: Shira Faigenbaum-Golovin, Duke University, Reconstruction, denoising, and studying the geometry of the base manifold in high-dimension space
SAS 4201It is common to assume that the data was sampled from a low-dimensional manifold in a high-dimensional space. In real life, neither the dimension of this manifold nor its geometry…
Geometry and Topology Seminar: Ruzica Mijic, Technical University of Vienna, An Introduction to Laguerre Geometry
SAS 1216In traditional Euclidean geometry, points serve as the foundational elements for constructing and analyzing space. In contrast, Laguerre geometry, a non-Euclidean geometry, uses oriented circles (or hyperspheres, in the context…
Algebra and Combinatorics Seminar: Corey Jones, NC State, Quantum cellular automata on fusion spin chains
SAS 4201Quantum cellular automata (QCA) are models of discrete-time unitary dynamics of quantum spin systems. They can be characterized algebraically as certain automorphisms of the associative algebra generated by local observables…
Nonlinear Analysis Seminar and Differential Equation Seminar: Shaoming Guo, University of Wisconsin Madison, Oscillatory integral operators on manifolds and related Kakeya and Nikodym problems
SAS 4201The talk is about oscillatory integral operators on manifolds. Manifolds of constant sectional curvatures are particularly interesting, and we will see that very good estimates on these manifolds can be expected. We…
Teaching and Learning Seminar: Matthew Voigt, Clemson University, Engaging in Critical Transformation of Math Programs to Disrupt the System
SAS 4201In this interactive seminar, we will examine how data (qualitative and quantitative) can be leveraged to interrogate, disrupt, and enact changes in introductory math programs. In particular, I will share…
Geometry and Topology Seminar: Marithania Silvero Casanova, Universidad de Sevilla, Positivity, fiberedness and link homology
ZoomKhovanov homology is a link invariant which categorifies Jones polynomial. In this talk we present several results concerning Khovanov homology of fibered positive links; in particular, we extend the result…
Applied Math Graduate Student Seminar:John Darges, NC State, Goal-Oriented Variance-Based Sensitivity Analysis for Uncovering Prior Hyperparameter Importance in Bayesian Inverse Problems s
SAS 4201The formulation of Bayesian inverse problems involves choosing prior distributions; choices that seem equally reasonable may lead to significantly different conclusions. We develop a computational approach to better understand the…
Algebra and Combinatorics Seminar: Mark Skandera, Lehigh University, Type-BC analogs of codominant permutations and unit interval orders
SAS 4201Permutations $w$ in $S_n$ for which the (type-A) Schubert variety $\Omega_w$ is smooth are characterized by avoidance of the patterns 3412 and 4231. The smaller family of codominant permutations, those…
