Seminar in Free Probability and Random Matrices
Speaker: Jamie Mingo
Title: The Infinitesimal Law of the real Wishart Ensemble, II
Abstract: I will continue from last week and compute the infinitesimal cumulants.
Wednesday, March 14, 2:15 p.m. Jeffery 319 - Number Theory Seminar
Speaker: Arpita Kar
Title: On the normal number of prime factors of Ramanujan Tau function
Abstract: We will discuss various results concerning $\omega(\tau(p))$, $omega(\tau(n))$, $\omega(\tau(p+1))$ where $\tau$ denotes Ramanujan Tau function and $\omega(n)$ denotes the number of prime factors of $n$ counted without multiplicity. This is work in progress with Prof. Ram Murty.
Wednesday, March 14, 3:30 p.m. Jeffery 319 - Curves Seminar
Speaker: Mike Roth
Title: Zak’s theorems on tangencies III
Abstract: We will prove Hartshorne’s conjecture on linear normality of subvarieties of small dimension, in the form of the restatement in terms of secant varieties.
Thursday, March 15, 5:30 p.m. Jeffery 118 - Math Club
Speaker: Greg Smith
Title: Realistic Expectations
Abstract: How many real roots should we expect a real polynomial to have? In this talk, we will convert this vague question into a well-posed mathematical problem. With the help of geometry, we will also provide the surprisingly beautiful solution.
