摘要:
We consider a semilinear elliptic problem -DELTAu=g(u)H(u-mu) in OMEGA, u=h on partial derivative OMEGA. Here H is the Heaviside function, mu is a parameter and OMEGA is the unit ball in R(n) with n greater-than-or-equal-to 3. Under suitable conditions on g, h and mu, we show that the problem has two solutions.
