“…Notice that it follows that W 0 (θ , φ ) = αβ γδW b (ϕ, ψ), [4]. Now, we introduce the Green function if W b (ϕ, ψ) = 0, then the nonhomogeneous BVPI (12), (8), (9) has a unique solution y(x) for which the formula [2] …”

“…The Fourier method for the partial differential equations with constants coefficient is a powerful tool [1][2][3][4][5]7]. But for the partial differential equation with piecewise constant coefficients this method is not developed much.…”
In this paper, we consider a fourth-order boundary value problem with impulse. We apply the Fourier method for solving of this problem arising in finding of transverse vibration of a string. We calculate the eigenvalues and eigenfunctions of the fourth-order boundary value problem for some ordinary differential equation with piecewise constant coefficient. We obtain a solution of the considered equation subject to initial data, boundary and transmission conditions at the point of discontinuity.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
