We propose a new approach to investigation of solvability of the Dirichlet problem for differential equations of infinite order. Namely, by using the embedding theorems for the energy spaces, obtained by the author in previous papers, the corresponding differential operator of infinite order is expressed as a sum of the main and subordinate operators of infinite order. The conditions under which the above Dirichlet problems are soluble, are established by using the main term of the corresponding differential operator.
Keywords: Dirichlet problem, equations of infinite order, solvability, subordinate terms.
