Hyperbolicity-Preserving Stochastic Galerkin Methods for Conservation Laws Based on Associative Truncated Products on Polynomial Spaces
Haroun Meghaichi, Yulong Xing
Stochastic Galerkin discretizations of nonlinear hyperbolic conservation laws may lose hyperbolicity because the standard pseudospectral product is generally nonassociative, leadin…

The Efficient Variable Time-stepping DLN Algorithms for the Allen-Cahn Model
YiMing Chen, Dianlun Luo, Wenlong Pei +1
We consider a family of variable time-stepping Dahlquist-Liniger-Nevanlinna (DLN) schemes, which is unconditional non-linear stable and second order accurate, for the Allen-Cahn eq…
