Sharp $H^{2}$ -regularity in dimensions $N \geq 5$ and beyond for two classes of elliptic problems with critical unbounded coefficients

Cristian Cazacu, Adelina Călina

We establish sharp parameter thresholds governing $H^{2}$ -regularity of weak solutions in $H_{0}^{1}$ for two classes of elliptic problems with critical unbounded perturbations, in dime…
