Abstract: The present paper was devoted to the study of asymptotical solution in small parameter of a boundary value problem for a second order elliptic equation with variable coefficients in a thin two-layer cylinder on the surface of which the coefficients of the equation have a discontinuity.
For studying asymptotics we used the idea of the A.Vishik and L.A.Lusternik method and the method of agreement of asymptotic expansions containing a small parameter.
