Irreducible characters taking root of unity values on p-singular elements
Gabriel Navarro, Geoffrey R. Robinson
In this paper we study finite p-solvable groups having irreducible complex characters chi in Irr(G) which take roots of unity values on the p-singular elements of G.
Prime fuzzy ideals over noncommutative rings
Gabriel Navarro, Oscar Cortadellas, F. J. Lobillo
In this paper we introduce prime fuzzy ideals over a noncommutative ring. This notion of primeness is equivalent to level cuts being crisp prime ideals. It also generalizes the one…
The valued Gabriel quiver of a wedge product and semiprime coalgebras
Gabriel Navarro
We make a first approach to the representation theory of the wedge product of coalgebras by means of the description of its valued Gabriel quiver. Then we define semiprime coalgebr…
On Endo-trivial Modules for p-Solvable Groups
Gabriel Navarro, Geoffrey R. Robinson
We prove a conjecture of J. Carlson, N. Mazza and J. Thévenaz; namely, we will prove that if is a finite -nilpotent group which contains a non-cyclic elementary Abelian -…
