| 摘 要： | In this paper we study the bifurcation problem for the following elliptic equalion (0.1) Here Lu= -△u has no eigenvalues and has only essential spectrum in R~N, the usual Lyapunov-Schmidt reduction cannot be used in problem (0.1). Meanwhile, L is not compact in H~1(R~N), of course, the method of topological degree is also |
