摘要：

It is shown that a lattice (gauge) theory can be obtained from a continuum theory via deformation of the standard differential calculus in such a way that functions and differentials no longer commute. Any lagrangian for a continuum theory which can be expressed in terms of differential forms is also defined for the deformed differential calculus. Using an integral which is naturally associated with the deformed differential calculus, one obtains an action for a lattice theory.
