It is known that many physical processes of a different nature, such as oscillations, thermal conductivity, diffusion, electrostatics, etc. are described by equations of elliptic type. In particular, some models such as hydro and gas dynamics consider elliptic equations. In this paper, we study a nonlocal boundary value problem with the Poincaré condition for an equation of elliptic - hyperbolic type of the second kind, i.e. for the equation where the line of degeneracy is the characteristic.
