We study the initial-boundary value problem for a general class of nonlinear dissipative equations on a half-line


where the nonlinear term (u,ux) depends on the unknown function u and its derivative ux and satisfies the estimate


with ρ,σ 0 and the linear operator K(u) is defined as follows


where the constants αn, αmR, n,m are integers, m>n, nM + 1, n is an even integer.

The aim of this paper is to prove the global existence of solutions to the initial-boundary value problem (0.1). We find the main term of the asymptotic representation of solutions.
