Global Bifurcation and Continuation in Nonlinear PDE's

10:30 AM-12:30 PM
Room: Rio Mar 5

In this minisymposium the speakers will discuss some recent developments in global bifurcation and continuation for nonlinear partial differential equations. In particular the talks will address new existence theorems, both local and global, for quasi-linear elliptic pde's in RN based on the degree theory of Fitzpatrick, Pejsachowicz and Rabier for Fredholm maps of index zero, and global bifurcation via regularization of a nonconvex functional depending on the gradient. Some global continuation results based on an abstract degree theory will be presented for the displacement equations of equilibrium of nonlinear elasticity with body forces and boundary displacements on corner or wedges domains.
