Finite-to-one fuzzy maps and fuzzy perfect maps

Francisco Gallego Lupiañez (1998)

Kybernetika

Similarity:

In this paper we define, for fuzzy topology, notions corresponding to finite-to-one and k -to-one maps. We study the relationship between these new fuzzy maps and various kinds of fuzzy perfect maps. Also, we show the invariance and the inverse inveriance under the various kinds of fuzzy perfect maps (and the finite-to-one fuzzy maps), of different properties of fuzzy topological spaces.

The Formal Construction of Fuzzy Numbers

Adam Grabowski (2014)

Formalized Mathematics

Similarity:

In this article, we continue the development of the theory of fuzzy sets [23], started with [14] with the future aim to provide the formalization of fuzzy numbers [8] in terms reflecting the current state of the Mizar Mathematical Library. Note that in order to have more usable approach in [14], we revised that article as well; some of the ideas were described in [12]. As we can actually understand fuzzy sets just as their membership functions (via the equality of membership function...

Fixed points of fuzzy monotone maps

Similarity:

The existence of fixed points for monotone maps on the fuzzy ordered sets under suitable conditions is proved.
