LSU Mathematics Student Colloquium
The goal of the LSU Mathematics Student Colloquium is to give both undergraduate and graduate students the opportunity to hear and interact with speakers from across the country, providing information and perspective possibly relevant to their graduate and postgraduate careers.
Each invited speaker will spend several days at LSU, giving multiple talks and making himself or herself available to undergraduates.
Talks are not confined to the math department but open to everyone. Those majoring in related fields are encouraged to come.
We are a chartered LSU student organization (constitution and bylaws). We are munificently funded by the Student Government Programming, Support, and Initiatives Fund (PSIF), and the LSU Mathematics Department. We are grateful for the generous past funding made by grants from the National Science Foundation (a VIGRE grant) and the Board of Regents.

Student Colloquium (Location: Lockett Hall 239; Tuesday, March 24, Time: 3:30pm)
Title: Totally concave regression
Abstract: We provide a general overview of regression under concavity shape constraints. In the multivariate setting, several notions of concavity exist, each with substantially different properties. We review these variants and highlight their key differences. Our main focus is on an approach based on total concavity, originally studied by T. Popoviciu, which avoids the usual curse of dimensionality and can be effective in practical applications.
