    On G-character tables for normal subgroups 
    Felipe Román, María Josefa; Pérez-Ramos, M. D.; Sotomayor, Víctor (Informa UK (National Inquiry Services Center), 2023-04-03)
    [EN] Let N be a normal subgroup of a finite group G. From a result due to Brauer, it can be derived that the character table of G contains square submatrices which are induced by the G-conjugacy classes of elements in N ...

    On zeros of irreducible characters lying in a normal subgroup 
    Felipe Román, María Josefa; Grittini, N.; Sotomayor, Víctor (Springer-Verlag, 2020-10)
    [EN] Let N be a normal subgroup of a finite group G. In this paper, we consider the elements g of N such that x(g)¿0 for all irreducible characters x of G. Such an element is said to be non-vanishing in G. Let p be a prime. ...

    Some Properties of Normal Subgroups Determined from Character Tables 
    Akhlaghi, Zeinab; Felipe Román, María Josefa; Jean-Philippe, M.K. (Springer-Verlag, 2024-05)
    [EN] G-character tables of a finite group G were defined in Felipe et al. (Quaest Math, 2022. https://doi.org/10.2989/16073606/16073606.2022.2040633). These tables can be very useful to obtain certain structural information ...

    Zeros of irreducible characters in factorised groups 
    Sotomayor, Víctor; Felipe Román, María Josefa; Martínez-Pastor, Ana (Springer-Verlag, 2019-02)
    [EN] An element g of a finite group G is said to be vanishing inG if there exists an irreducible character of G such that (g)=0; in this case, g is also called a zero of G. The aim of this paper is to obtain structural ...
