Abstract : It is indicated that a series of problems in mathematical physics (theory of waveguides, hydrodynamics, and others) can be considered as boundaryvalue problems for the secondorder equation the second derivative of u with respect to t = Auf(t), 0 = or < t = or < T, where u(t) is a function to be determined and f(t) is a given function of a complex Banach space E and A in a bounded linear operator. The solution u(t) is sought which satisfies a system of boundary conditions.
