    Products of groups and class sizes of pi-elements 
    Felipe Román, María José; Martínez-Pastor, Ana; Sotomayor, Víctor (Springer-Verlag, 2020-02)
    [EN] We provide structural criteria for some finite factorised groups G = AB when the conjugacy class sizes in G of certain pi-elements in A boolean OR B are either pi-numbers or pi'-numbers, for a set of primes pi. In ...

    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 ...
