High-order positivity-preserving well-balanced schemes: combining flux globalization with modified Patankar deferred correction methods
Positivity-preserving schemes for hyperbolic balance laws are typically built from the Zhang-Shu limiter and strong-stability-preserving Runge-Kutta (SSP-RK) time stepping, at the cost of a restrictive time-step condition. The modified Patankar deferred correction (mPDeC) method removes this restric
