摘要

We study the Dirichlet problem for the p-Laplacian in a conical domain with the homogeneous boundary condition on the lateral surface of a cone with vertex at the origin. We assume that the variable exponent p = p(x) is separated from 1 and ∞ and denote by Ω, the intersection of the cone with the unit (n - 1)- dimensional sphere. We prove that (ⅰ) if p satisfies the Lipschitz condition and δΩ is of class C~(2+β), then the solution to the Dirichlet problem is O(|x|~λ) in a neighborhood of the origin, where λ is the sharp exponent of tending to zero of solutions to the same Dirichlet problem for the p(0)-Laplacian and (ⅱ) if p satisfies the Hoelder condition, p(0) = 2, and δΩ is of class C~(1+β), then the solution to the Dirichlet problem is O(|x|~(λ_0)) in a neighborhood of the origin, where λ_0 is the sharp exponent of tending to zero of solutions to the same Dirichlet problem for the Laplace operator. Bibliography: 18 titles.
