Unique solvability of a non-local problem for mixed type equation with fractional derivative

E. T. Karimov, A. S. Berdyshev, N. A. Rakhmatullaeva

In this work we investigate a boundary problem with non-local conditions for mixed parabolic-hyperbolic type equation with three lines of type-changing with Caputo fractional deriv…
