Some Notes on Spaces of Ideals and Computable Topology [PDF]

, 2020
We show some basic results on the characterization of quasi-Polish spaces in terms of spaces of ideals, with an emphasis on the connections with computable topology.

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

Almost Quasi Continuity and Weak Quasi Continuity for Multifunctions Between an Ideal Topological Space and a Bitopological Space

European Journal of Pure and Applied Mathematics
This paper introduces four classes of continuous multifunctions defined from an ideal topological space into a bitopological space, namely upper almost quasi $\tau^\star(\sigma_1,\sigma_2)$-continuousmultifunctions, lower almost quasi $\tau^\star ...

Second approximation of local functions in ideal topological spaces

Acta et commentationes Universitatis Tartuensis de mathematica, 2019
This paper gives a new dimension to discuss the local function in ideal topological spaces. We calculate error operators for various type of local functions and introduce more perfect approximation of the local functions for discussing their properties ...

Ideals on Generalized Topological Spaces

International Journal of Analysis and Applications, 2020
In this paper, we define the g-closure operator and investigate some of its crucial properties. We also introduce and study the concept of ψg-classes and generalized compatibly of generalized topology with ideal. This work is generalization of [4].

On star Rothberger spaces modulo an ideal

Applied General Topology
In this article, we introduce the ideal star-Rothberger property by coupling the notion of a star operator to that of an ideal Rothberger space, after which some of its topological characteristics are analysed. By creating relationships between a numbers

Fixed Point Property of Variable Exponent Cesàro Complex Function Space of Formal Power Series under Premodular

Journal of Function Spaces, 2022
We have defined the variable exponent of the Cesàro complex function space of formal power series. We have constructed the prequasi-ideal generated by s-numbers and this new space of complex functions. We present some topological and geometric structures

Residuated Lattices with Noetherian Spectrum

Mathematics, 2022
In this paper, we characterize residuated lattices for which the topological space of prime ideals is a Noetherian space. The notion of i-Noetherian residuated lattice is introduced and related properties are investigated.

On sequence space derived by the domain of q-Cesàro matrix in ℓ space and the associated operator ideal

, 2021
We study the sequence space X p q obtained by using the domain of q-analogue of the Cesaro matrix C ( q ) = ( c i j q ) defined by c i j q = { q j − 1 [ i ] q ( 1 ≤ j ≤ i ) , 0 ( j > i ) , where the notation [ i ] q has the usual meaning.

Ideals on fuzzy topological spaces

Applied Mathematical Sciences, 2014
Fuzzy ideal set and fuzzy local function of fuzzy ideals with fuzzy topologies were introduced and studied by D. Sarker [10]. The purpose of this paper deals with new sort of fuzzy ideal and fuzzy local function namely fuzzy ideal and r-fuzzy open local function.
