Multiplicity results for mixed local-nonlocal equations with singular and critical exponential nonlinearity in R^2 (2503.08261v1)

Abstract: In this article, we prove the existence of at least two positive weak solutions for a mixed local-nonlocal singular problem in the presence of critical exponential nonlinearity in dimension two. The novelty of this work is the inclusion of a variable singular exponent in the context of mixed operator and critical exponential nonlinearity in R^2. Our approach is based on sub-solution super-solution technique, combined with variational methods.
