Quantification of Topological Concepts Using Ideals
نویسندگان
چکیده
We introduce certain ideals of real-valued functions as a natural generalization of filters. We show that these ideals establish a canonical framework for the quantification of topological concepts, such as closedness, adherence, and compactness, in the setting of approach spaces. 2000 Mathematics Subject Classification. 54A05, 54D30.

An introduction to topological hyperrings
In this paper, we define topological hyperrings and study their basic concepts which supported by illustrative examples. We show some differences between topological rings and topological hyperrings. Also, by the fundamental relation $\Gamma^{*}$, we indicate the role of complete parts (saturated subsets) and complete hyperrings in topological hyperrings and specially we show that if every (clo...
متن کاملAlgebraic and topological aspects of quasi-prime ideals
In this paper, we define the new notion of quasi-prime ideal which generalizes at once both prime ideal and primary ideal notions. Then a natural topology on the set of quasi-prime ideals of a ring is introduced which admits the Zariski topology as a subspace topology. The basic properties of the quasi-prime spectrum are studied and several interesting results are obtained. Specially, it is pro...

In this paper we introduce the notion of fuzzy bitopological ideals .The concept of fuzzy pairwise local function is also introduced here by utilizing the q-neighborhood structure for a fuzzy topological space .These concepts are discussed fuzzy bitopologies and several relations between different fuzzy bitopological ideals .
متن کاملz_R-Ideals and z^0_R -Ideals in Subrings of R^X
Let X be a topological space and R be a subring of RX. By determining some special topologies on X associated with the subring R, characterizations of maximal fixxed and maximal growing ideals in R of the form Mx(R) are given. Moreover, the classes of zR-ideals and z0R-ideals are introduced in R which are topological generalizations of z-ideals and z0-ideals of C(X), respectively. Various c...
متن کاملHc-convergence Theory of L-nets and L-ideals and Some of Its Applications
In this paper we introduce and study the concepts of HC-closed set and HClimit (HC-cluster) points of L-nets and L-ideals using the notion of almost N -compact remoted neighbourhoods in L-topological spaces. Then we introduce and study the concept of HL-continuous mappings. Several characterizations based on HC-closed sets and the HC-convergence theory of L-nets and L-ideals are presented for H...
