The second author has shown that Carlitz’s q-Boulli numbers can be represented as an integral by the q-analogue of the ordinary p-adic invariant measure (see [
Let G be the fundamental group of a graph of groups and X the corresponding universal tree. We consider the extension of the action of G on X to an action of th
We give an overview of the work done so far towards a proof of the k(GV)-conjecture, that is R. Brauer’s k(B)-problem for p-solvable groups. In particular, we
In this paper, we construct large families of characteristically nilpotent Lie algebras by considering deformations of the Lie algebra (g)4(m,m-1) of type Qn,wh
In this article, we introduce and study the notion of λ-finitely embedded modules (a O-finitely embedded module is just a finitely embedded module). We extend
Let F be a regularity for near-rings and F(R) the largest FR-regular ideal in R. In the first part of this paper, we introduce the concepts of maximal Fmodular
Let G be a finite group and let e be the exponent of its Schur multiplier M(G). Schur [6] has shown that e2 is a divisor of the order |G| of G. We say that M(G)
We introduce the graded bialgebra deformations, which explain the lifting method of Andruskiewitsch and SchneiderWe also relate these graded bialgebra deformati
We construct a new family of simple modules over an orthogonal complex Lie algebra associated with Gelfand-Zetlin formulae for simple finitedimensional modules
