Global Multiplicity and Comparison Principles for Singular Problems driven by Mixed Local-Nonlocal Operators

R. Dhanya, Sarbani Pramanik

We study a singular elliptic problem driven by a mixed local-nonlocal operator of the form \begin{equation*} \begin{aligned} -Δ_p u + (-Δ_q)^s u &= \fracλ{u^δ} + u^r \text{ in } Ω\…
