Resumen:
A multichannel S-matrix framework for singular quantum mechanics
(SQM) subsumes the renormalization and self-adjoint extension
methods and resolves its boundary-condition ambiguities. In
addition to the standard channel accessible to a distant (??asymptotic??)
observer, one supplementary channel opens up at each coordinate
singularity, where local outgoing and ingoing singularity
waves coexist. The channels are linked by a fully unitary S-matrix,
which governs all possible scenarios, including cases with an apparent
nonunitary behavior as viewed from asymptotic distances.
