Front capturing schemes for nonlinear PDEs with a free boundary limit

February 22, 2018 - 3:30pm - Vincent Hall 16
Li Wang
Abstract: Evolution in physical or biological systems often involves interplay between nonlinear interaction among the constituent “particles,” and convective or diffusive transport, which is driven by density dependent pressure. When the pressure-density relationship becomes highly nonlinear, the evolution equation converges to a free boundary problem as a stiff limit. In terms of numerics, the nonlinearity and degeneracy bring great challenges, and there is lack of standard mechanism to capture the propagation of the front in the limit. In this talk, I will introduce a numerical scheme for tumor growth models based on a prediction-correction reformulation, which naturally connects to the free boundary problem in the discrete sense. As an alternative, I will present a variational method for a class of continuity equations (such as the Keller-Segel model) using the gradient flow structure, which has built-in stability, positivity preservation and energy decreasing property, and serves as a good candidate for capturing the stiff pressure limit.

Associativity and Integrability

March 1, 2018 - 3:30pm - Vincent Hall 16
Ordway Visitor - Rui Loja Fernandes
Abstract: A fundamental result of Lie theory is Lie’s Third Theorem which states that every finite dimensional Lie algebra integrates to a Lie group. This result fails for infinite dimensional Lie algebras (e.g., Banach Lie algebras) and it also fails for (finite dimensional) Lie algebroids. But every reasonable Lie algebra (finite or infinite dimensional) integrates to a local Lie group and every Lie algebroid integrates to a local Lie groupoid. On the other hand, a classical theorem of Mal’cev states that a local group is enlargeable to a group if and only if it is global associative. This talk will be an introduction to Lie algebroids and groupoids, focusing on the failure of Lie’s Third Theorem and its relationship to the failure of associativity.
