On the Volterra property of a boundary problem with integral gluing   condition for mixed parabolic-hyperbolic equation
  In the present work we consider a boundary value problem with gluing conditions of integral form for parabolic-hyperbolic type equation. We prove that the considered problem has the Volterra property. The main tools used in the work are related to the method of the integral equations and functional analysis.
