Banach spaces from the point $\varepsilon = 0$. A convergent iterative procedure is proposed for the construction of solutions as parts
of series in powers of $\varepsilon$ with pole at the point $\varepsilon = 0$.}, number={3}, journal={Ukrainsâ€™kyi Matematychnyi Zhurnal}, author={ZhuravlevV. F.}, year={2018}, month={Mar.}, pages={366-378} }
