Recent results on the stability of time dependent sets and their application to bifurcation problems (Q966209)

This paper contains several results on the relationship between conditional and unconditional stability of time-dependent sets of ordinary differential equations. Here, the unconditional stability properties of an invariant set depend on stability properties of a larger set. This dependence is analyzed first in the general and then in the period case. The results are finally applied to bifurcation problems for periodic differential equations.
