An energy-based discontinuous Galerkin method for semilinear wave equations
Daniel Appelo, Thomas Hagstrom, Qi Wang +1
We generalize the energy-based discontinuous Galerkin method proposed in [SIAM J. Num. Anal., 53(6):2705-2726, 2015.] to second-order semilinear wave equations. A stability and con…
Stationary Ring and Concentric-Ring Solutions of the Keller-Segel Model with Quadratic Diffusion
Lin Chen, Fanze Kong, Qi Wang
This paper investigates the Keller-Segel model with quadratic cellular diffusion over a disk in with a focus on the formation of its nontrivial patterns. We obtain ex…
Phase transitions and bump solutions of the Keller-Segel model with volume exclusion
Jose A. Carrillo, Xinfu Chen, Qi Wang +2
We show that the Keller-Segel model in one dimension with Neumann boundary conditions and quadratic cellular diffusion has an intricate phase transition diagram depending on the ch…
An Exact Auxiliary Variable Gibbs Sampler for a Class of Diffusions
Qi Wang, Vinayak Rao, Yee Whye Teh
Stochastic differential equations (SDEs) or diffusions are continuous-valued continuous-time stochastic processes widely used in the applied and mathematical sciences. Simulating p…
