Boundary Triples and Self-Adjointness
A simple variation of the not so popular approach to self-adjoint extensions via boundary triples is discussed. The idea is exemplified through a series of examples, including the one-dimensional hydrogen atom, free hamiltonian in an interval and spherically symmetric potentials. At the end, important self-adjoint extensions of a quantum particle hamiltonian in a multiply connected domain are found.
