# Events for March 28, 2018 from General and Seminar calendars

## Number Theory Seminar

**Time:** 1:15PM - 2:15PM

**Location:** BLOC 220

**Speaker:** Solly Parenti, University of Wisconsin

**Title:** *Unitary CM fields and the Colmez conjecture*

**Abstract:**In 1993, Pierre Colmez conjectured a relation between the Faltings height of a CM abelian variety and certain log derivatives of L-functions associated to the CM type, generalizing the classical Chowla-Selberg formula. I will discuss how we can extend the known cases of the conjecture to a certain class of unitary CM fields using the recently proven average version of the conjecture.

## AMUSE

**Time:** 6:00PM - 7:00PM

**Location:** BLOC 220

**Speaker:** Dr. Anne Shiu, Texas A&M University, Department of Mathematics

**Title:** *Recovering parameters in mathematical models*

**Abstract:**Ordinary differential equation (ODE) models are very common in applications. This talk addresses, for ODE models that are linear, the problem of when parameters can be recovered from data. I will highlight how techniques from differential algebra reduce the problem to one that can be solved using linear algebra and combinatorics. I will also highlight some examples coming from biology. No background will be assumed.
