Index Theorem in Finite Noncommutative Geometry
arXiv:0706.3078 · doi:10.1143/PTPS.171.228
Abstract
Index theorem is formulated in noncommutative geometry with finite degrees of freedom by using Ginsparg-Wilson relation. It is extended to the case where the gauge symmetry is spontaneously broken. Dynamical analysis about topological aspects in gauge theory is also shown.
