Ukr. Mat. Zh. - 2018. - 70, № 10. - pp. 1374-1381
The conditions of well-posedness of a nonlocal boundary-value problem are established for a second-order linear partial differential equation in an unbounded strip in the case where the real parts of the roots of its characteristic equation are different and nonzero.
