A Comment on the K-theory Meaning of the Topology of Gauge Fixing
Cesar Gomez
Abstract
Based on the recently discovered K-theory description of D-branes in string theory a K-theory interpretation of the topology of gauge conditions for four dimensional gauge theories, in particular 't Hooft abelian projection, is presented. The interpretation of the dyon effect in terms of K-1 is also discussed. In the context of type IIA strings, D-p branes are also interpreted as gauge fixing singularities.
