Some Fixed Point Theorems in Fuzzy n-Normed Spaces [PDF]

, 2010
The main purpose of this paper is to study the existence of a fixed points in fuzzy n-normed spaces. we proved our main results, a fixed point theorem for a self mapping and a common fixed point theorem for a pair of weakly compatible mappings on fuzzy n-

Construction of 3D Indoor Topological Models Based on Improved Face Sorting

ISPRS International Journal of Geo-Information
Indoor location-based services and applications need to obtain information about the indoor spatial layouts and topological relationships of indoor spaces. The 3D city modeling data standard CityGML describes the indoor geometric and semantic information

Homeomorphic spaces in the plane [PDF]

, 1971
The idea of topological equivalence, or homeomorphism, is one of the most basic in any study of topology. In this paper, pairs of spaces imbedded in the plane are compared to determine whether or not they are homeomorphic. The decisions are based on four

Proto-metrizable fuzzy topological spaces [PDF]

, 1999
summary:In this paper we define for fuzzy topological spaces a notion corresponding to proto-metrizable topological spaces. We obtain some properties of these fuzzy topological spaces, particularly we give relations with non-archimedean, and metrizable ...

Topological Quantum Field Theory and the Geometric Langlands Correspondence [PDF]

, 2013
In the pioneering work of A. Kapustin and E. Witten, the geometric Langlands program of number theory was shown to be intimately related to duality of GL-twisted N=4 super Yang-Mills theory compactified on a Riemann surface. In this thesis, we generalize

Functional product topology: A common framework of the topological sum, the product topology and the functional topology of pointwise convergence

Journal of Hebei University of Science and Technology, 2015
Based on the topological sum, for X being a discrete topological space, we prove that the product topology generated by some topological spaces is equal to the topology of pointwise convergence related to X.

Local homogeneity in fuzzy topological spaces

International Journal of Mathematics and Mathematical Sciences, 2006
Three types of local homogeneity in L-topological spaces are introduced and studied, and each is characterized and proved to be a good extension of local homogeneity in ordinary topological spaces. Many implications concerning them are introduced.

The Topology of Spaces of Polygons [PDF]

, 2011
We study the topology of spaces of polygons in Euclidean space, viewed up to translations. The main results concern the structure of the homology groups and of the cohomology rings of the spaces.

Countable Fuzzy Topological Space and Countable Fuzzy Topological Vector Space

Journal of Mathematical and Fundamental Sciences, 2015
This paper deals with countable fuzzy topological spaces, a generalization of the notion of fuzzy topological spaces. A collection of fuzzy sets F on a universe X forms a countable fuzzy topology if in the definition of a fuzzy topology, the condition of
