Abstract
Existence is proved for a family of soliton-like solutions for the non linear evolution equation u(t)+uu(x)+u(xxx)-u(xxxxx)=0. The problem is reduced to investigating the fixed points of the operator (Au)(x) = i ntegral-infinity/-infinity k(x-y)u2(y)dy. Integral-infinity/-infinity k(x) = 1, whose action is considered in a cone of Frechet functions th at are continuous on the real axis.
