### Some results for jumping nonlinearities

E. Norman Dancer

#### Abstract

We discuss the calculation of critical groups for jumping nonlinearities as the resonance set is crossed. In addition, we produce a counter-example showing that even "generically" the resonance set is more complicated than previously thought.
