Finite Subgroups of Group Rings: A survey
Leo Margolis, Ángel del Río
In the 1940's Graham Higman initiated the study of finite subgroups of the unit group of an integral group ring. Since then many fascinating aspects of this structure have been dis…

An application of blocks to torsion units in group rings
Andreas Bächle, Leo Margolis
We use the theory of blocks of cyclic defect to prove that under a certain condition on the principal p-block of a finite group G the normalized unit group of the integral group ri…

The Herzog-Schönheim Conjecture for small groups and harmonic subgroups
Leo Margolis, Ofir Schnabel
We prove that the Herzog-Schönheim Conjecture holds for any group of order smaller than . In other words we show that in any non-trivial coset partition $\{g_i U_i\}_{i=1…
