The Relativistic Gamov Vectors and Poincare Semigroup
Protvino, 1996.- p.17, refs.:11.


The main points of the nonrelativistic rigged Hilbert space formulation of unstable states are generalized for the relativistic case. The consideration is made in the framework which may be interpreted as a relativistic Friedrichs model admitting the explicit construction of Gamov vectors. Instead of a nonrelativistic semigroup of time translation, here naturally arises the Poincare semigroup.
