A Bifurcation Theorem

A description of the classical bifurcation problem will be found in Minorsky [l, Chapter V] and Andronov and Chaikin [2, Chapter 6]. Here the functions /i and /2 are required to be analytic and the proof depends on the series expansion guaranteed by the analyticity. In [3, Chapter IV, §6], K. 0. Friedrichs establishes a bifurcation theorem which does not require analyticity but uses the implici...

A fixed point result for a new class of set-valued contractions

In this paper, we introduce a new class of set-valued contractions and obtain a xed point theoremfor such mappings in complete metric spaces. Our main result generalizes and improves many well-known xed point theorems in the literature.

A bifurcation theorem for noncoercive integral functionals

In this paper we study the existence of critical points for noncoercive functionals, whose principal part has a degenerate coerciveness. A bifurcation result at zero for the associated differential operator is established.

A bifurcation theorem for Darwinian matrix models

Matrix models are widely used to describe the discrete time dynamics of structured populations (i.e., biological populations in which individuals are classified into discrete categories such as age, size, etc.). A fundamental biological question concerns population extinction and persistence, i.e., the stability or instability of the extinction state versus the existence of stable positive equi...

A Torus Bifurcation Theorem with Symmetry

A general theory for the study of degenerate Hopf bifurcation in the presence of symmetry has been carried out only in situations where the normal form equations decoupte into phase/amplitude equations. In this paper we prove a theorem showing that in general we expect such degeneracies to lead to secondary torus bifurcations. We then apply this theorem to the case of degenerate Hopf bifurcatio...
