ON ISOMORPHISM OF TWO BASES INMORREY-LEBESGUE TYPE SPACES

Double system of exponents with complex-valued coefficients is considered. Under some conditions on the coefficients,we prove that if this system forms a basis for the Morrey-Lebesguetype space on [−π; π], then it is isomorphic to the classical systemof exponents in this space
