Existence results for mixed local and nonlocal elliptic equations involving singularity and nonregular data

Souvik Bhowmick, Sekhar Ghosh

In this paper, we prove the existence of weak, veryweak and duality solutions to a class of elliptic problems involving singularity and measure data which is given by: $-Δu+(-Δ)^…
