Abstract
The Minkowski space-time algebra Cl-3,Cl-1 is a powerful tool for studying the theory of electromagnetism and special relativity. In this paper, we intend to establish generalizations of Titchmarsh theorems for certain classes of functions, namely Lipschitz functions in the space L-p(R-3,R-1 , Cl-3,Cl-1) for 1 p <= 2.
