GENERALIZED PRODUCT TOPOLOGY [PDF]
Communications of the Korean Mathematical Society, 2013 Summary: Similarly to the Tychonoff product, we introduce the concept of generalized product topology which is different from the notion of product of generalized topologies in [\textit{Á. Császár}, Acta Math. Hung. 123, No. 1--2, 127--132 (2009; Zbl 1224.54003)] for a generalized topology and obtain some properties of it.

Only 3-generalized metric spaces have a compatible symmetric topology
Open Mathematics, 2015 We prove that every 3-generalized metric space is metrizable. We also show that for any ʋ with ʋ ≥ 4, not every ʋ-generalized metric space has a compatible symmetric topology.

Theory of Generalized Sets in Generalized Topological Spaces
Journal of New Theory, 2021 Several specific types of generalized sets (briefly, g-T_g-sets in generalized topological spaces (briefly, T_g-spaces have been defined and investigated for various purposes from time to time in the literature of T_g-spaces.

Fuzzy $\mu^*$-Open Set and Fuzzy $\mu^*$-Continuous Function [PDF]
Sahand Communications in Mathematical Analysis, 2023 The prime goal of this article is to initiate the notion of fuzzy $\mu^*$-open(closed) sets and fuzzy $\mu^*$-continuous functions and characterize them.

The topology of general cosmological models*
Classical and Quantum Gravity, 2022 Abstract Is the Universe finite or infinite, and what shape does it have? These fundamental questions, of which relatively little is known, are typically studied within the context of the standard model of cosmology where the Universe is assumed to be homogeneous and isotropic.

More properties of generalized open sets in generalized topological spaces
Demonstratio Mathematica, 2022 Sarsak [M. S. Sarsak, On some properties of generalized open sets in generalized topological spaces, Demonstr. Math. 46 (2013), no. 2, 415–427] studied some properties of generalized open sets in generalized topological spaces (GTSs); the primary purpose

On functions between generalized topological spaces
Applied General Topology, 2013 This paper investigates generalized topological spaces and functions between such spaces from the perspective of change of generalized topology. In particular, it considers the preservation of generalized connectedness properties by various classes of ...
