A priori error estimates for a Hybrid High-Order method on variable-exponent Leray-Lions problems
André Harnist, Romain Mottier
We derive a priori error estimates for the Hybrid High-Order (HHO) discretization of variable-exponent Leray--Lions problems introduced in a companion convergence study. HHO method…

A Hybrid High-Order method for variable-exponent Leray-Lions problems with convergence under minimal regularity
André Harnist, Romain Mottier
We consider a homogeneous Dirichlet problem for nonlinear elliptic equations in divergence form with Leray--Lions fluxes of variable growth. The class includes the variable-exponen…
