in this paper, we investigate the zassenhaus conjecture for $psl(4,3)$ and $psl(5,2)$. consequently, we prove that the prime graph question is true for both groups.
we investigate the classical h.~zassenhaus conjecture for integral group rings of alternating groups $a_9$ and $a_{10}$ of degree $9$ and $10$, respectively. as a consequence of our previous results we confirm the prime graph conjecture for integral group rings of $a_n$ for all $n leq 10$.
throughout this dissertation r is a commutative ring with identity and m is a unitary r-module. in this dissertation we investigate submodules of multiplication , prufer and dedekind modules. we also stat the equivalent conditions for which is ring , wher l is a submodule of afaithful multiplication prufer module. we introduce the concept of integrally closed modules and show that faithful mu...
Using the Luthar–Passi method, we investigate the classical Zassenhaus conjecture for the normalized unit group of the integral group ring of the Rudvalis sporadic simple group Ru. As a consequence, for this group we confirm Kimmerle’s conjecture on prime graphs.
For a finite group $G$ and $U: = U(\mathbb{Z}G)$, the of units integral ring $G$, we study implications structure on abelianization $U/U'$ $U$. We pose questions connections between exponent $G/G'$ as well ranks torsion-free parts $Z(U)$, center $U$, $U/U'$. show that originating from known generic constructions in $\mathbb{Z}G$ are well-behaved under projection $U$ to our have positive answer ...
