2-27-2025: Siddhi Krishna, “Braids: What, How and Why”
Speaker: Siddhi Krishna (Columbia) *Where and when: 4:30-5:30pm in ENGR 209 Title: Braids: What, How and Why Abstract: Braids are one of my favorite objects within math — in addition to being really useful, they help unify many different areas of math, including algebra, topology, geometry, combinatorics, and more! In this talk, I’ll tell you…Continue Reading 2-27-2025: Siddhi Krishna, “Braids: What, How and Why”
2-21-2025: Karl Schwede, “Measuring singularities over the complex numbers, in characteristic p> 0, and over the p-adic integers.”
Speaker: Karl Schwede (University of Utah) Fri. Feb. 21, 3:00 pm, Bell 2269 Title: Measuring singularities over the complex numbers, in characteristic p > 0, and over the p-adic integers. Abstract: Given a polynomial equation, one can consider it over the complex numbers and measure its singularities using geometric or analytic techniques. One may also…Continue Reading 2-21-2025: Karl Schwede, “Measuring singularities over the complex numbers, in characteristic p> 0, and over the p-adic integers.”
