In this paper, we prove some fixed point theorems for some weaker forms of compatibility satisfying a contractive condition of integral type on d-complete Hausdorff topological spaces.  ...  Our results extend and generalize some well known previous results.  ...  The d-complete symmetrizable spaces form an important class of d-complete topological spaces. Other examples of dcomplete topological spaces may be found in Hicks and Rhoades [10] .  ...

Helical magnetic ordering in Tb completely suppressed by uniaxial tension: Evidence of electronic topological transition and support for the nesting hypothesis

A. Vl. Andrianov, D. I. Kosarev, A. I. Beskrovnyi
2000 Physical Review B (Condensed Matter)  
This range diminishes rapidly as uniaxial tension is applied, and at tensions over p*ϭ680 bar the helical ordering is completely suppressed.  ...  The experiment supports the hypothesis that the type of magnetic ordering in rare-earth metals is determined by Fermi surface topology, which can in turn be altered by uniaxial deformation.  ...  As the FS topology is different in Y and Gd, the change in FS topology would definitely occur in this system at some x.  ...

Complete topologized posets and semilattices

Taras Banakh, Serhii Bardyla
2022 arXiv   pre-print
In this paper we discuss the notion of completeness of topologized posets and survey some recent results on closedness properties of complete topologized semilattices.  ...  By the down-completeness (and ↑κ-completeness) of X the chain D has inf DD (and sup DD). The continuity of h implies that f (inf D) ∈ f (D) ⊂ f (D) =C (and f (sup D) ∈ f (D) ⊂ f (D) =C).  ...  If the topologized semilattice X is down-complete (and ↑κ-complete), then so is the topologized semilattice Y . Proof. Assume that the topologized semilattice X is down-complete (and ↑κ-complete).  ...

Tanvi Jain, S. Kundu
2008 Mathematica Slovaca  
A metric space (X, d) is said to have an Atsuji completion if its completion ($$ \hat X $$, d) is an Atsuji space.  ...  We also characterize topologically those metrizable spaces whose completions are Atsuji spaces.  ...  Acknowledgementº The authors would like to thank Prof. L'. Holá for her suggestions, in particular for suggesting improvements in Theorem 3.6, and the referee for comments and observations.  ...

On the lattice of Fréchet-Nikodým topologies

Cecilia Brook Weakley
1987 Journal of Mathematical Analysis and Applications  
Weber [9] and Brook and Traynor [4] independently showed that the exhaustive FN topologies form a complete Boolean algebra and the existence of relative complements is the basis of the Lebesgue decomposition  ...  Drewnowski, who first studied FN topologies systematically [5] , observed that the collection of FN topologies on an algebra forms a complete lattice with 0 and 1.  ...  The set FN(.d) of all FN topologies on x2, ordered by inclusion, is a complete lattice, Proof: By 1. 2 and 1.4, E(d) is a complete distributive lattice with largest element E.  ...

Such categories provide a setting for general topology and topological algebra when I is the category of sets or a category of algebras.  ...  This is a survey for the working mathematician of the theory of initially complete categories.  ...  The pair (d, T) is called an initially complete category if T: d + 2' is topological, and a topological category under the additional conditions mentioned in Section 1.

Also, we introduce and investigate the notions of q-continuous and q-algebraic complete lattices. Finally, we give and examine the quasi Lawson topology on a complete lattice.  ...  This topology is always larger than or equal to the Scott topology and smaller than or equal to the strong Scott topology. Results concerning the above topology are given.  ...  The authors would like to thank the referee for very helpful comments and suggestions.  ...
