Weberything except the inhomogeneous initial conditions. These will be called separated solutions. Of course, not every solution will be found this way, but we have a trick up our sleeve: the superpo-sition principle guarantees that linear combinations of separated solutions will also satisfy both the equation and the homogeneous boundary conditions.

WebJul 15, 2024 · Hi, I've been reading Brillouin's 'Wave Propagation in Periodic Structures'. About the following equation $$\nabla^2u_1+\frac{\omega^2_0}{V_0^2}u_1 = R(r)$$ Brillouin states that "it is well known that such an equation possesses a finite solution only if the right-hand term is orthogonal to all solutions of the homogeneous equation:" … Webinhomogeneous boundary condition so instead of being zero on the boundary, u(or @u=@n) will be required to equal a given function on the boundary. The second kind is a \source" or \forcing" term in the equation itself (we usually say \source term" for the heat equation and \forcing term" with the wave equation), so we’d have u t= r2u+ Q(x;t) Webwe show that how small the initial data are for the global solutions to exist. Finally, we prove the instability of the standing wave by combining the former results. Keywords … igor gorelyshev
