commutative groups of hyperbolic transformations of the unit disk acting in the Lebesgue space $L_p, p > 1$, and obtain an
effective criterion for the operators from the considered Banach algebra to be Fredholm operators.}, number={11}, journal={Ukrains’kyi Matematychnyi Zhurnal}, author={Mozel’, V. A.}, year={2017}, month={Nov.}, pages={1515-1523} }
