Bifurcation of solutions of elliptic problems: local and global behaviour
José Luis Gámez, Juan F. Riuz · Topological Methods in Nonlinear Analysis · 2004
Here we study the local behavior of the continua in the case of Neumann boundary conditions, pointing out some qualitative differences with the Dirichlet case. We also combine local and global behavior of the bifurcating sets to obtain existence of solutions and study of their sign for some related problems.
