Failure of analyticity-radius growth in energy-canceling fluid models
Ke Chen, Haina Li, Quoc-Hung Nguyen +1
We prove that exact quadratic energy cancellation alone does not force growth of the spatial analyticity radius. On , we construct an explicit symmetric, translation-…

Sharp decay characterization for partially dissipative hyperbolic systems of balance laws
Ling-Yun Shou, Jiang Xu, Ping Zhang
The partially dissipative systems that characterize many physical phenomena were first pointed out by Godunov (1961), then investigated by Friedrichs-Lax (1971) who introduced the…

Global well-posedness of 3-D density-dependent incompressible MHD equations with variable resistivity
Hammadi Abidi, Guilong Gui, Ping Zhang
In this paper, we investigate the global existence of weak solutions to 3-D inhomogeneous incompressible MHD equations with variable viscosity and resistivity, which is sufficientl…
