Group actions, deformations, polygroup extensions, and group presentations
Serban A. Basarab, Thomas W. Müller
Generalizing classical extension theory, we solve a Schreier-type extension problem for polygroups by groups. As a consequence, we obtain a method for computing a presentation for…
A more general framework for coGalois theory
Serban A. Basarab
The paper is an extended version of a talk given at the International Conference: Experimental and Theoretical Methods in Algebra, Geometry and Topology, which took place June 21--…
Arithmetic-arboreal residue structures induced by Prufer extensions : An axiomatic approach
Serban A. Basarab
We present an axiomatic framework for the residue structures induced by Prufer extensions with a stress upon the intimate connection between their arithmetic and arboreal theoretic…
Embedding theorems for actions on generalized trees, I
Serban A. Basarab
Using suitable deformations of simplicial trees and the duality theory for median sets, we show that every free action on a median set can be extended to a free and transitive one.…
