Title: An Introduction to Lie Groups from a Geometric Perspective
 

Fernando Morera | Tulane University
Abstract:
Throughout this talk I am going to build a naive path from differential geometry to the definition of a Lie group. I will provide several examples as well as an intuition behind foundational definitions and propositions.

Title: So... everything is a signal?
 

Sergio Villamarin | Tulane University
Abstract:
In this very introductory talk I'll go over classical signal processing from a math perspective, I'll try to present some of the technical terms that show up and explain their importance from a mathematical perspective.  Finally, I'll illustrate an application of some signal processing tools in seismology and some cute graphs from a current project I have been working at.

Title: What's Your Communication Style? Communicating Mathematics

Will Tran | Tulane University
Abstract:
In this interactive math-adjacent leadership training activity, we will assess and evaluate your personal communication style. We will see applications of communication style when communicating mathematics. Finally, we will learn about how to flex our communication style to get what we want when working with students, other T.A.s, and professors.

Title: Expected Sum Negativity Over Random Quantum States

Victor Bankston | Tulane University
Abstract:

The Sum Negativity is a property of a quantum state, which can be considered as a computational resource. We calculate the expected value of the Sum Negativity over random quantum states, drawn from the unique distribution on pure states which is invariant under unitary transformations.

Title: Mathematical Models for Biochemical Oscillation

Sang-Eun Lee | Tulane University
Abstract:

In this talk, we discuss what is mathematical modelling and how to derive the models for biochemical oscillation. If the time permits, we may discuss circadian rhythms.

Title: Improved quasi-Monte Carlo methods for Integrating High Dimension Functions

Lin Li | Tulane University
Abstract:

Approximating the integral of a function in a high dimension more accurate and efficient is a challenge. We proposed several improved quasi-Monte Carlo methods for integrating high dimension functions from two different ways. First, we use the control variate method to reduce variation error. Second, we use Voronoi weight and surrogate points interpolation methods to reduce the discrepancy error. In each method, we give the error simulation with different function integration. Various methods to generate pseudo-random and quasi-random sequences are implemented to compare the different methods.

Title: An introduction to sports analytics and an analysis of MVP voting

Louis Nass | Tulane University
Abstract:

Sports analytics have had a major influence on the sports world. Analytics provide more information of players on and off the field that allow teams to become more efficient not only in performance, but economically as well. Here we will briefly discuss the emergence of sports analytics and its impact in leagues across the US. Afterwards, we will do our own ‘analytics’ with respect to the NBA Most Valuable Player voting. We will construct generalized linear models that input individual player statistics and output our estimated MVP vote count. The goal here is to comment on which predictors are most/least influential to MVP voting and to apply and predict the 2019 NBA MVP.
