Norm inflation with infinite loss of regularity at general initial data for nonlinear wave equations in Wiener amalgam and Fourier amalgam spaces
Divyang G. Bhimani, Saikatul Haque
We study the strong ill-posedness (norm inflation with infinite loss of regularity) for the nonlinear wave equation at every initial data in Wiener amalgam and Fourier amalgam spac…

A note on the optimal boundary regularity for the planar generalized -Poisson equation
Saikatul Haque
In this note, we establish sharp regularity for solutions to the following generalized - Poisson equation $$-\ div\ \big(\langle A\nabla u,\nabla u\rangle^{\frac{p-2}{2}}A\nabla…
