EXISTENCE OF AT LEAST TWO SOLUTIONS FOR DOUBLE PHASE PROBLEM
Bin Ge, Wen-Shuo Yuan · Journal of Applied Analysis & Computation · 2022
This paper concerns with a class of double phase Dirichlet problem depending of one real parameter. Under some appropriate assumptions, we obtain the existence of at least two solutions for this problem using a direct consequence of the celebrated Pucci and Serrin theorem. Our results generalize some existing results.
