Charge conjugation from space-time inversion in QED: discrete and continuous groups
CPT groups space-time inversion Lorentz and Poincar´ e groups
2010/11/29
We show that the CPT groups of QED emerge naturally from the PT and P (or T )subgroups of the Lorentz group. We also find relationships between these discrete groups and continuous groups, like the co...

A conjugation-free geometric presentation of a funda-mental group is a presentation with the natural topological gener-ators x1, . . . , xn and the cyclic relations.

Suppose X is a non-singular complex surface defined over \R, which is a complete intersection constructed by the method of a small perturbation, and Y=X/\conj is its quotient by the complex conjugatio...

It is proved that, for a (henselian) local field K and for a fixed Lubin-Tate splitting f over K, the metabelian local Artin map (?, K)f: B(K, f) \tilde{\rightarrow} Gal (K(ab)2 / K) satisfies the Gal...

In this paper we prove a formula involving the canonical anti-automorphism c of the mod-p Steenrod algebra.
