An efficient Legendre-Galerkin spectral method and its error analysis for a one-dimensional parabolic equation with Dirichlet-type non-local boundary conditions are presented in this paper. The spatial discretization is based on Galerkin formulation and the Legendre orthogonal polynomials, while the time derivative is discretized by using the symmetric Euler finite difference schema. The stability and convergence of the semi-discrete spectral approximation are rigorously set up by following a novel approach to overcome difficulties caused by the non-locality of the boundary condition. Several numerical tests are included to confirm the efficacy of the proposed method and to support the theoretical results.

Existence and uniqueness theorems are proved for a parabolic equation satisfying various kinds of non-local boundary conditions. Applications of these results are made to the physical situation in which a non-metallic conductor is in contact with a perfect conductor or with a well stirred fluid, and the conductor (or the fluid) is allowed to undergo a change of phase.
