چکیده

Given a homomorphism of groups f : G ? H f:G\rightarrow H , we construct topological space alttext="upper X Subscript f"> X encoding="application/x-tex">X_f such that its group homeomorphisms A u t left-parenthesis f Baseline right-parenthesis"> A u t stretchy="false">( stretchy="false">) encoding="application/x-tex">Aut(X_f) is isomorphic to G"> encoding="application/x-tex">G homotopy classes self-homotopy equivalences alttext="script E E encoding="application/x-tex">\mathcal {E}(X_f) encoding="application/x-tex">H and the natural map between alttext="f"> encoding="application/x-tex">f . In addition, consider realization problems involving homology groups, automorphisms.

Homomorphisms on Topological Groups from the Perspective of Bourbaki-boundedness

In this note we study some topological properties of bounded sets and Bourbaki-bounded sets. Also we introduce two types of Bourbaki-bounded homomorphisms on topological groups  including, n$-$Bourbaki-bounded homomorphisms and$hspace{1mm}$ B$-$Bourbaki-bounded homomorphisms. We compare them to each other and with the class of continuous homomorphisms. So, two topologies are presented on them a...

Separate and Joint Continuity of Homomorphisms Defined on Topological Groups

In this paper we prove the following theorem. “Let H be a countably Čech–complete topological group, X be a topological space and (G, ·, τ) be a topological group. If f : H ×X → G is a separately continuous mapping with the property that for each x ∈ X, the mapping h 7→ f(h, x) is a group homomorphism, then for each q–point x0 ∈ X the mapping f is jointly continuous at each point of H ×{x0}.” W...

Souslin measurable homomorphisms of topological groups

1. In a recent paper [18], A. Kleppner proved that every Haar measurable homomorphism 4 : G ~ H between locally compact groups G, H is continuous. This result also follows from a measure theoretic result by D. H. Fremlin [8], (see also [9, 19]), which provides a technique to prove measurability of uncountable unions of measurable sets. The purpose of this note is to present a different and new ...

Categorically Proper Homomorphisms of Topological Groups

We extend the Dikranjan-Uspenskij notions of c-compact and h-complete topological group to the morphism level, study the stability properties of the newly defined types of maps, such as closure under direct products, and compare them with their counterparts in topology. We assume Hausdorffness only when our proofs require us to do so, which leads to new results and the affirmation of some facts...

Homomorphisms of Knot Groups on Finite Groups

We describe trial and error computer programs for finding certain homomorphisms of a knot group on a special projective group LF(2, p), p prime, and programs to evaluate #i(3TC ; Z) where 9TC is a finitely sheeted branched covering space of S3 associated with such a homomorphism. These programs have been applied to several collections of examples, in particular to the Kinoshita-Terasaka knots, ...
