Fuzzy Markov chains: uncertain probabilities.
We consider finite Markov chains where there are uncertainties in some of the transition probabilities. These uncertainties are modeled by fuzzy numbers. Using a restricted fuzzy matrix multiplication we investigate the properties of regular, and absorbing, fuzzy Markov chains and show that the basic properties of these classical Markov chains generalize to fuzzy Markov chains.
Pure filters and stable topology on BL-algebras
In this paper we introduce stable topology and -topology on the set of all prime filters of a BL-algebra and show that the set of all prime filters of , namely Spec() with the stable topology is a compact space but not . Then by means of stable topology, we define and study pure filters of a BL-algebra and obtain a one to one correspondence between pure filters of and closed subsets of Max(), the set of all maximal filters of , as a subspace of Spec(). We also show that for any filter...
