A decoupled energy-stable mixed finite element method for Poisson-Nernst-Planck-Navier-Stokes equations
Yanmei Peng, Ying Yang, Yi Zhang
We propose a novel linearized mixed finite element method for the Poisson-Nernst-Planck-Navier-Stokes (PNPNS) system. Specifically, the method combines a staggered time discretizat…

Bounded Continuous weak quasiregular mappings that fail to be quasiregular
Stanislav Hencl, Yi Ru-Ya Zhang
We show that, in dimensions , continuity and boundedness do not restore the Sobolev regularity conjecture of Iwaniec and Martin for weakly quasiregular mappings below the…
