Abstract

Abstract The purpose of this article is to apply the concept of the spectral triple, the starting point for the analysis of noncommutative spaces in the sense of Connes (1994), to the case where the algebra |A contains both bosonic and fermionic degrees of freedom. The operator |D of the spectral triple under consideration is the square root of the Dirac operator and thus the forms of the generalized differential algebra constructed out of the spectral triple are in a representation of the Lorentz group with integer spin if the form degree is even and half-integer spin if the form degree is odd. However, we find that the 2-forms, obtained by squaring the connection, contain exactly the components of the vector multiplet representation of the supersymmetry algebra. This allows to construct an action for supersymmetric Yang-Mills theory in the framework of noncommutative geometry.
