    Simplicity of normal subgroups and conjugacy class sizes 
    Beltrán, Antonio; Felipe Román, María Josefa (Springer Verlag (Germany), 2014-12)
    Given a finite group G which possesses a non-abelian simple normal subgroup N having exactly four G-class sizes, we prove that N is isomorphic to PSL(2,2a) with a≥2. Thus, we obtain an extension for normal subgroups of the ...

    The D-pi-property on products of pi-decomposable groups 
    Kazarin, L.S.; Martínez-Pastor, Ana; Pérez-Ramos, M. D. (Springer-Verlag, 2020-11-01)
    [EN] The aim of this paper is to prove the following result: Let pi be a set of odd primes. If the group G = AB is the product of two p-decomposable subgroups A = A(pi) x A(pi') and B = B-pi x B-pi', then G has a unique ...
