Abstract

In a domain D ⊂ ℝn divided by a hyperplane Σ into two parts D(1) and D(2), we consider a p(x)-Laplace type equation with a small parameter and with exponent p(x) that has a logarithmic modulus of continuity in each part of the domain and undergoes a jump on Σ when passing from D(2) to D(1). Under the assumption that the equation uniformly degenerates with respect to the small parameter in D(1), we establish the Hölder continuity of solutions with Hölder exponent independent of the parameter.
