Abstract:
A special solution of Abel's ordinary differential equation of the first kind u′x+u3−tu−x=0 is considered, which describes the behaviour of a broad spectrum of solutions of partial differential equations with a small parameter in the neighbourhood of cusp points of their slowly varying equilibrium positions. The existence of this special solution is demonstrated; an asymptotic formula for it as |x|→∞, t→−∞ is constructed and substantiated.
