A direct proof of Wignefs theorem on transition probability preserving maps between pure states of a quantum system and a more precise statement of the theorem are provided. The mathematical proof presented here shows that the result should be as obvious to every one as it has been to Wigner.

A general formulation for discrete-time quantum mechanics, based on Feynman's method in ordinary quantum mechanics, is presented. It is shown that the ambiguities present in ordinary quantum mechanics (due to noncommutativity of the operators), are no longer present here. Then the criteria for the u
We present a formal calculation of the infrared singularity structure of the fermion propagator in QED based on the Faddeev-Kulish asymptotic solution. The Renormalization program is reviewed in the context of the BPHZ subtraction scheme and a refinement of the Renormalization group methods is emplo
