A counterexample to Feit's Problem VIII on decomposition numbers
Gabriel Navarro, Benjamin Sambale
We find a counterexample to Feit's Problem VIII on the bound of decomposition numbers. This also answers a question raised by T. Holm and W. Willems.
On defects of characters and decomposition numbers
Gunter Malle, Gabriel Navarro, Benjamin Sambale
We propose upper bounds for the number of modular constituents of the restriction modulo of a complex irreducible character of a finite group, and for its decomposition numbers…
Loewy lengths of centers of blocks
Burkhard Külshammer, Benjamin Sambale
Let B be a block of a finite group with respect to an algebraically closed field F of characteristic p>0. In a recent paper, Otokita gave an upper bound for the Loewy length LL(ZB)…
On centers of blocks with one simple module
Pierre Landrock, Benjamin Sambale
Let G be a finite group, and let B be a non-nilpotent block of G with respect to an algebraically closed field of characteristic 2. Suppose that B has an elementary abelian defect…
