Finite speed of propagation and local boundary conditions for wave equations with point interaction s
(2005) In Proceedings of the American Mathematical Society 133(10). p.30713078 Abstract
 We show that the boundary conditions entering in the definition of the selfadjoint operator Delta(A,B) describing the Laplacian plus afinite number of point interactions are local if and only if the corresponding wave equation phi = Delta(A,B)phi has finite speed of propagation.
