摘要	We study multiplicity of solutions of the following elliptic problems in which critical and supercritical Sobolev exponents are involved: -Delta u = g(x, u) + lambda h(x, u) in Omega and u = 0 on partial derivative Omega, -div(\del u\(p-2)del u) = g(x, u) + lambda h(x, u) in Omega and u = 0 on partial derivative Omega, where Omega is a smooth bounded domain in R-N, p > 1, lambda is a parameter, and lambda h(x, u) is regarded as a perturbation term of the problems. Except oddness with respect to u in some cases, we do not assume any condition on h. For the first problem, we get a result on existence of three nontrivial solutions for \lambda\ small in the case where g is superlinear and lim sup(\t\-->infinity) g(x, t)/\t\(2-1) is suitably small. We also prove that the first problem has 2k distinct solutions for \lambda\ small when g and h are odd and there are k eigenvalues between lim(t-->0) g(x, t)/t and lim(\t\-->infinity) g(x, t)/t. For the second problem, we prove that it has more and more distinct solutions as lambda tends to 0 assurning that g and h are odd and g is superlinear and lim(\t\-->infinity) g(x, t,)/\t\(p-1) = 0.
