  Imperfect bifurcations arising from elliptic boundary value problems
■ 概要
  In this paper we study some semilinear elliptic equations with a Robin condition. It is shown that the imperfect bifurcation occurs in some elliptic differential equations with the Robin condition and that the bifurcation diagram under the Neumann condition "breaks" by perturbing the boundary condition. It is also proved that these bifurcating branches are characterized by the number of critical points of the solutions.(pp.663-684)
