In [24], a new algorithm for thinning multi- dimensional black and white digital images by using cell complexes was presented. Such cell complexes allow a discrete partition of the space and the algorithm preserves topolog- ical and geometrical properties of the image. In this paper, we present a parallel adapta- tion of such algorithm to P systems, by introducing some concepts of Algebraic Topology in the Membrane Computing framework. The chosen model for the implementation is tissue-like P systems with promoters, inhibitors and priorities.}, url = {http://www.gcn.us.es/10BWMC/10BWMCvolII/papers/MCThinning_bwmc.pdf}, author = {Ra{\'u}l Reina-Molina and Daniel D{\'\i}az-Pernil and Miguel A.
