摘要	We consider the perturbed Schrodinger equation {(u(x) -> 0) (-epsilon 2 Delta u + V(x)u = P(x)vertical bar u vertical bar p-2u + K(x)vertical bar u vertical bar 2- 2u) (as vertical bar x vertical bar -> infinity) (for x epsilon RN) where N >= 3, 2 = 2N/(N - 2) is the Sobolev critical exponent, p epsilon (2, 2*), P(x) and K(x) are bounded positive functions. Under proper conditions on V we show that it has at least one positive solution provided that epsilon <= epsilon; for any m epsilon N, it has m pairs of solutions if epsilon <= epsilon(m); and suppose there exists an orthogonal involution tau : R-N -> R-N such that V(x), P(x) and K(x) are tau- invariant, then it has at least one pair of solutions which change sign exactly once provided that epsilon <= epsilon, where epsilon and epsilon(m) are sufficiently small positive numbers. Moreover, these solutions u(epsilon) -> 0 in H-1(R-N) as epsilon -> 0.
