In this section we consider the group [A,ΩX] of homotopy classes of maps of the space A into the loop space ΩX and the homomorphisms f*: [B,ΩX] → [A,ΩX] induced by a continuous map f: A → B. We deal only with spaces with base points and maps and homotopies that ...

QUASI-ISOMORPHISMS AND GROUPS OF QUASI-HOMOMORPHISMS. This paper investigates to which extent a self-small mixed Abelian group G of finite torsion-free rank is determined by the groups Hom(G,C) where C is chos... ALBRECHT,ULRICH - 《Journal of Algebra & Its Applications》...
The automorphism group of a finitely generated free group is the normal closure of a single element of order 2. If $m$ is less than $n$ then a homomorphism $Aut(F_n)\to Aut(F_m)$ can have cardinality at most 2. More generally, this is true of homomorphis
such as those related to the tetrahedron and the right-hand screw principle.Homomorphisms, mappings between groups, play a crucial role in understanding relationships between groups. The Lorenz group, for instance, is a set of transformations that preserve the Lorentz metric. By defining...
