Second quantization and gauge invariance
Dan Solomon
It is well known that the single particle Dirac equation is gauge invariant. This means that observable quantities, such as the current density, are not affected by a gauge transfo…

A Comment on the calculation of the Lie algebra cocycle in the book Loop Groups
Dan Solomon
An expression for the Lie algebra cocycle corresponding to the central extension of the group GLres(H) is derived in the book Loop Groups [1]. It will be shown in this paper that s…

A demonstration of the necessity of regularization in order to avoid inconsistent results in quantum field theory
Dan Solomon
We will examine a particular mathematical derivation in a paper by P. Falkensteiner and H. Grosse (F&G) [1]. In [1] a quantity "delta(A)" is defined. This quantity is generated whe…
