Topic: Umbral calculus, a method for symbolic computation
Christophe Vignat - Tulane University
Abstract: Umbral calculus is a computation method that represents a sequence of numbers or functions as a sequence of moments. It allows a significant simplification in the computation of some sequences, such as those associated with orthogonal polynomials.
This talk will introduce umbral calculus through some examples such as Hermite or Gegenbauer polynomials, and will show some applications.

Topic: Four weeks on the nonlinear Schrodinger equation
Katerina Gkogkou and Ken McLaughlin – Tulane University
Abstract: This will be an informal working group, learning about the long time asymptotic behavior of the defocusing NLS equation, based on a combination of Riemann-Hilbert and d-bar techniques.
