On the LS-category of homomorphism of almost nilpotent groups
Nursultan Kuanyshov
We prove the equality $\cat(ϕ)=\cd(ϕ)$ for epimorphisms between torsion-free, finitely generated almost nilpotent groups and . In addition, we prove the equality…

On the LS-category of homomorphisms of groups with torsion
Nursultan Kuanyshov
We prove the equality $\cat(ϕ)=\cd(ϕ)$ for homomorphisms between finitely generated abelian groups and , where for the torsion subgroups of …
