Study of Gamow States in the Rigged Hilbert Space with Tempered Ultradistributions
A. L. De Paoli, M. A. Estevez, M. C. Rocca +1
In this work we show that it is possible to extend analitically, and with the use of tempered ultradistributions, the pseudonorm defined by T. Berggren for Gamow states. We define…

The Wheeler Propagator
C. G. Bollini, M. C. Rocca
We study the half advanced and half retarded Wheeler Green function and its relation to Feynman propagators. First for massless equation. Then, for Klein-Gordon equations with arbi…
