Math Colloquium today
by David Wright 21 Apr '23

21 Apr '23

Hello: There is a math colloquium today: Speaker: Yudong Cao, Chief Technology Office and Co-Founder of Zapata Computing Title: Quantum-enahnced machine learning and optimization The abstract is below. This talk is via Zoom but it will be shown on the projector in MSCS 101 at 3:30 PM. The Zoom link is https://okstate-edu.zoom.us/j/96799414512 Since this is virtual, there will be some refreshments before the talk in the department 4th floor lounge at 3PM, instead of afterwards. Please join us either online or in MSCS 101 David Wright Abstract: I will introduce the subject of quantum computing, followed by discussions on how it can be applied to machine learning and optimization. We have done experiments in the past years on quantum devices for enhancing machine learning applications, especially generative modeling capabilities. I will also discuss the significance role of tensor networks, a highly related area to quantum, in our quest for quantum advantage.

Math Colloquia Coming Up
by David Wright 13 Apr '23

13 Apr '23

Dear friends: Tomorrow (Friday, April 14) there will be a math colloquium at 3:30 PM in MSCS 101: Speaker: Qing Han, Notre Dame University Title: Regularity of singular solutions of differential equations Abstract is below. Refreshments will follow at 4:30 in the department fourth floor lounge. Next week the final spring colloquium will be Friday, April 21st: Dr. Yudong Cao, CTO and cofounder of Zapata Computing Title: Quantum-enhanced machine learning and optimization This will be a virtual talk on zoom (details to be communicated later) but you can also come to MSCS 101 at 3:30 PM where we will have a community viewing. On Friday April 28th, in place of a colloquium we will have the Department Awards Meeting in the French Lounge of the Student Union, where we will recognize our students' successes. On Friday May 5th, we will have the Math Department Student Research Poster Session at the MLSC. Please come join us, David Wright Math Colloquium Friday, April 14, 3:30 PM, MSCS 101 Speaker: Qing Han, Notre Dame University Title: Regularity of singular solutions of differential equations Abstract: In many important geometric differential equations, solutions are not necessarily regular. When singularity occurs, we still intend to explore whether solutions possess regularity of a certain degree. The structure of the singular sets, where solutions become singular, plays an important role. In this talk, we focus on one case. The singular sets are isolated. To study the regularity of solutions near the singular sets, we investigate asymptotic expansions of solutions. The talk is intended for a general audience.

Math Colloquium on Friday April 7
by David Wright 06 Apr '23

06 Apr '23

Hi: There is a math colloquium tomorrow April 7 at 3:30 PM in MS 101: Speaker: YanYan Li of Rutgers University Title: Gradient estimates for elliptic equations from composite material See below for the abstract. Refreshments at 4:30 in the department lounge. Hope to see you there, David Wright Abstract: In this talk, we discuss gradient estimates for a class of divergence form elliptic equations with piecewise smooth coefficients. Such equations arise from the study of composite materials. The novelty of these estimates is that, even though they depend on the shape and on the size of the surfaces of discontinuity of the coefficients, they are independent of the distance between these surfaces. The talk is intended for a general audience.
