The weighted Hardy spaces ep (B; ρ) of harmonic functions are introduced on simply connected domains B with rectifiable boundaries. Boundary properties of functions in these spaces are investigated, the solvability of the Dirichlet problem is established, while its solution with its derivatives are estimated. Approximation properties of the system of harmonic polynomials in ep (B;ρ)) are studied. © 2018, Eurasian Mathematical Journal.
