On bifurcations of cusps

Zbigniew Szafraniec


Let Ft, where t∈R, be an analytic family of plane-to-plane mappings with F0 having a critical point at the origin. The paper presents effective algebraic methods of computing the number of those cusp points of Ft, where 0<|t|≪1, emanating from the origin at which Ft has a positive/negative local topological degree.
