The volterra property of some problems with the Bitsadze–Samarskii-type conditions for a mixed parabolic-hyperbolic equation

We consider problems with the Bitsadze–Samarskii-type conditions for a mixed parabolic-hyperbolic equation with noncharacteristic type change curve. We prove theorems on the unique existence of regular and strong solutions and the Volterra property for the problems under consideration.
