V({ \infty })= 0的非线性Schroedinger方程极小节点解的存在性

Existence of minimal nodal solutions for the Nonlinear Schroedinger equations with V ({\infty}) = 0

Marco G. Ghimenti, Anna Maria Micheletti

摘要:

考虑RN中的问题Δu+V(x)u = f '(u).这里,非线性具有双幂行为,并且V在正交对合下是不变的,其中V({ \infty })= 0。给出了一对正一次变号解的存在性定理。

英文摘要:

We consider the problem Δu+V(x)u = f'(u) in RN. Here the nonlinearity has a double power behavior and V is invariant under an orthogonal involution, with V ({\infty}) = 0. An existence theorem of one pair of solutions which change sign exactly once is given.
