| Descripción |
We present a unified description of gravity and electromagnetism in the framework
of a Z 2 noncommutative differential calculus. It can be considered as a "discrete
version" of Kaluza-Klein theory, where the fifth continuous dimension is replaced
by two discrete points. We derive an action which coincides with the dimensionally
reduced one of the ordinary Kaluza-Klein theory.

Recently, Connes [1, 2] has proposed a new construction of noncommutative geometry
where the basic objects are an algebra A (possibly noncommutative), a Hilbert space
on which the algebra acts, and a "Dirac operator" on the Hilbert space. The al...
