Abstract
The main goal of this paper is to introduce the notion of twisted partial action of groupoids. We generalize the theorem about the existence of an enveloping action, also known as the globalization theorem, and show that the crossed products of the twisted partial action and of its associated twisted global action are Morita equivalent. Finally, we generalize the concepts of partial projective representation and partial Schur multiplier for a groupoid, and we show the interaction between groupoid partial projective representions and groupoid twisted partial actions.
