Type space on a purely measurable parameter space [PDF]

open access: yes, 2005
Several game theoretical topics require the analysis of hierarchical beliefs, particularly in incomplete information situations. For the problem of incomplete information, Hars´anyi suggested the concept of the type space.

Neutrosophic -Topological spaces

open access: yesNeutrosophic Sets and Systems, 2020
In this paper, the concept of neutrosophic 􀀀topological spaces is introduced. We dene and study the properties of neutrosophic 􀀀open sets, 􀀀closed sets, 􀀀interior and 􀀀closure. The set of all generalize neutrosophic pre-closed sets GNPC( ) and the set of all neutrosophic -open sets in a neutrosophic topological space (X; ) can be considered as examples

A Hybrid Approach to Micro Vague Topological Space via Neutrosophic Topological Space [PDF]

open access: yesNeutrosophic Sets and Systems
Plenty of topologists are exploring and discovering multiple forms of topological spaces. The chief objective of the current enquiry is to establish and evaluate an original hybrid topological space named Neutrosophic Micro Vague Topological Space. When

On the Structure of Topological Spaces

open access: yesAxioms, 2022
The structure of topological spaces is analysed here through the lenses of fibrous preorders. Each topological space has an associated fibrous preorder and those fibrous preorders which return a topological space are called spatial.

Z2-topology in nonsymmorphic crystalline insulators: Mobius twist in surface states [PDF]

open access: yes, 2015
It has been known that an anti-unitary symmetry such as time-reversal or charge conjugation is needed to realize Z2 topological phases in non-interacting systems. Topological insulators and superconducting nanowires are representative examples of such Z2

The character of free topological groups I

open access: yesApplied General Topology, 2005
A systematic analysis is made of the character of the free and free abelian topological groups on uniform spaces and on topological spaces. In the case of the free abelian topological group on a uniform space, expressions are given for the character in ...

GTI-space : the space of generalized topological indices [PDF]

open access: yes, 2008
A new extension of the generalized topological indices (GTI) approach is carried out torepresent 'simple' and 'composite' topological indices (TIs) in an unified way.

Topological Space-Time Crystal

open access: yesPhysical Review Letters, 2022
We introduce a new class of out-of-equilibrium noninteracting topological phases, the topological space-time crystals. These are time-dependent quantum systems which do not have discrete spatial translation symmetries, but instead are invariant under discrete space-time translations.

p-topological Cauchy completions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
The duality between “regular” and “topological” as convergence space properties extends in a natural way to the more general properties “p-regular” and “p-topological.” Since earlier papers have investigated regular, p-regular, and topological Cauchy ...

Profinite algebras and affine boundedness

open access: yes, 2016
We prove a characterization of profinite algebras, i.e., topological algebras that are isomorphic to a projective limit of finite discrete algebras. In general profiniteness concerns both the topological and algebraic characteristics of a topological ...
