Abstract
We compute the time-dependent Schrodinger propagator with a point interaction in dimension n<or=3 including the new cases of n=2 and the most general interaction supported by a point for n=1. We also give the small-time asymptotics for n<or=3. The case n=2 has the peculiarity of involving logarithmic terms in the expansion.Keywords
