Abstract: A boundary-value problem for a second order parabolic equation on a half-line is considered. A uniform asymptotic approximation to a solution to within any power of $t^{-1}$ is constructed and substantiated.
Bibliography: 8 titles.
Keywords: asymptotic expansion, small parameter, boundary-value problem, method of matching.
