Colloquia
Compilation of colloquium talks given in the department.
Math Colloquium: Joe P. Chen (Colgate University), The cutoff phenomenon for exclusion processes on graphs with open boundaries Sep 10, 2020 from 12:30 PM to 01:30 PM Zoom link: https://ccny.zoom.us/j/92057419965,
Joe P. Chen (Colgate University), The cutoff phenomenon for exclusion processes on graphs with open boundaries A fundamental question in the study of Markov chains is the convergence to a stationary distribution. As an example, how many shuffles does it take to fully mix a standard deck of 52 cards? Answering this "mixing time" question requires understanding notions of convergence in finite Markov chains, and the spectral theory of Markov matrices.

Amanda Folsom (Amherst College)-Mock modular and quantum modular forms
Mathematics Colloquium: Amanda Folsom (Amherst College) Mar 02, 2021 from 12:30 PM to 01:30 PM Zoom Link: https://ccny.zoom.us/j/92057419965,
Mock modular and quantum modular forms
Mathematics Colloquium: Alexander B. Vladimirsky (Cornell University)- Agreeing to Disagree in Anisotropic Crowds Mar 18, 2021 from 12:30 PM to 01:30 PM Zoom Link: https://ccny.zoom.us/j/92057419965,
Agreeing to Disagree in Anisotropic Crowds How do the choices made by individual pedestrians influence the large-scale crowd dynamics? What are the factors that slow them down and motivate them to seek detours? What happens when multiple crowds pursuing different targets interact with each other?
Mathematics Colloquium: Regularity of anisotropic minimal surfaces Apr 13, 2021 from 12:30 PM to 01:30 PM Zoom Link: https://ccny.zoom.us/j/92057419965,
Abstract I will present regularity theorems for weak minimal surfaces with respect to anisotropic surface energies, extending the celebrated isotropic counterparts proved by Allard.
Mathematics Colloquium: Carina Curto(The Pennsylvania State University)-Graphs, network motifs, and threshold-linear algebra in the brain Apr 27, 2021 from 12:30 PM to 01:30 PM Zoom Link: https://ccny.zoom.us/j/92057419965,
Threshold-linear networks (TLNs) are commonly-used rate models for modeling neural networks in the brain. Although the nonlinearity is quite simple, it leads to rich dynamics that can capture a variety of phenomena observed in neural activity: persistent activity, multistability, sequences, oscillations, etc
Mathematics Colloquium: Dr. Linda V. Green - Mathematical Modeling for Healthcare Capacity Planning May 04, 2021 from 12:30 PM to 01:30 PM Zoom Link: https://ccny.zoom.us/j/92057419965,
Determining capacity needs for hospital beds, physicians, nurses and other healthcare resources is critical in providing timely care for patients as has been clearly illustrated over this past year of the COVID pandemic.
