Abstract: An inhomogeneous Dirichlet boundary value problem for a singularly perturbed homogeneous convection-diffusion equation with constant coefficients is considered in a half-plane. Convection is assumed to be directed orthogonally to the half-plane boundary away from it. Assuming that the boundary function is from the space $C^{2,\lambda}$, $0<\lambda<1$, an unimprovable estimate for the solution bounded at infinity is obtained in the appropriate Hölder norm.

Key words: singularly perturbed equation, convection–diffusion, problem in a half-plane, unimprovable a priori estimates, Hölder spaces.
