We investigate the classical Zassenhaus conjecture for the normalized unit group of the integral group ring of the simple Janko group J1. As a consequence, for this group we confirm Kimmerle’s conjecture on prime graphs.

Using the Luthar–Passi method, we investigate the classical Zassenhaus conjecture for the normalized unit group of the integral group ring of the Suzuki sporadic simple group Suz. As a consequence, for this group we confirm the Kimmerle’s conjecture on prime graphs.

The aim of this study was to evaluate operative laparoscopy in comparison with conventional laparotomy for intestinal resection and anastomosis in dogs. Eighteen adult dogs were equally and randomly divided into 3 groups: Group I: Intestinal anastomosis was performed extracorporeally, by laparoscopic-assisted surgery, in which a 5cm loop of small bowel was exteriorized through a mini-laparotomy...

Abstract I present explicit examples of generalizations in relativistic quantum mechanics. First all, discuss the generalized spin-1/2 equations for neutrinos. They have been obtained by means Gersten-Sakurai method derivations arbitrary-spin equations. Possible physical consequences are discussed. Next, it is easy to check that both Dirac algebraic equation Det ( <mml:ma...

We consider the Zassenhaus conjecture for the normalized unit group of the integral group ring of the McLaughlin sporadic group McL. As a consequence, we confirm for this group the Kimmerle’s conjecture on prime graphs.

In a previous article we have defined an action of the Iwahori-Hecke algebra Coxeter group W on free module with basis indexed by involutions in W. this paper show that specialization at parameter 0 has simple description.
