The classical Dirichlet problem for a second-order strongly elliptic systemwith constant coefficients in a Jordan domain is considered. We show that thesolution of the problem can be represented as a functional series in powers ofthe parameter, which determines the deviation of the system operator from theLaplacian. This series converges uniformly in the closure of the region underthe assumption that the boundary of the region and the boundary functionsatisfy the sufficient regularity conditions: the trace of a conformal mappingof the domain onto a circle composed with the boundary function belongs to theHolder class with exponent greater than 1/2.
