For systems of this kind in the indicated spaces, we establish the correct solvability of the Cauchy problem. It is shown that, for each $\beta>1,$ the space ${S_0^\beta}’$ of Gelfand and Shilov distributions is the class of well-posedness of this problem.}, number={10}, journal={Ukrains’kyi Matematychnyi Zhurnal}, author={LitovchenkoV.
