THEORETICAL SEMINAR ANNOUNCEMENT

On October 26, 2006 at 11:00, Matej Pavsic, from Ljubljana University, Slovenia will give a seminar entitled:

“On the physics in Clifford space: an extra structure of spacetime”

Abstract:

Starting from the geometric calculus based on Clifford algebra, I will present the idea that physical quantities are Clifford aggregates ('polyvectors'), and that spacetime should be replaced by 16-dimensional Clifford space. The latter space can provide a realization of the Kaluza-Klein unification of fundamental interactions. I will introduce the basic concepts related to flat and curved Clifford space, and discuss the generalized Dirac equation which involves polyvector valued fields. Yang-Mills gauge fields naturally occur in such approach as parts of the generalized spin connection.
