چکیده
We show that a group is GVZ-group if and only it flat group. the nilpotence class of bounded by number distinct degrees irreducible characters. also certain CM-groups can be characterized as GVZ-groups whose character values lie in prime field.

Groups and Ultra-groups
In this paper, in addition to some elementary facts about the ultra-groups, which their structure based on the properties of the transversal of a subgroup of a group, we focus on the relation between a group and an ultra-group. It is verified that every group is an ultra-group, but the converse is not true generally. We present the conditions under which, for every normal subultra-group of an u...
متن کاملFlat Connections, Braid Groups and Quantum Groups
In this talk, I will describe how quantum groups serve as a useful means of expressing the monodromy of certain integrable, first order PDE’s. A fundamental, and paradigmatic result in this context is the Kohno–Drinfeld theorem. Roughly speaking, it asserts that the representations of Artin’s braid groups on n strands given by the universal R-matrix of a quantum group describe the monodromy of ...
متن کاملSelmer Groups as Flat Cohomology Groups
Given a prime number p, Bloch and Kato showed how the p8-Selmer group of an abelian variety A over a number field K is determined by the p-adic Tate module. In general, the p-Selmer group Selpm A need not be determined by the mod p Galois representation Arps; we show, however, that this is the case if p is large enough. More precisely, we exhibit a finite explicit set of rational primes Σ depen...

15 صفحه اولOn local gamma factors for orthogonal groups and unitary groups
In this paper, we find a relation between the proportionality factors which arise from the functional equations of two families of local Rankin-Selberg convolutions for irreducible admissible representations of orthogonal groups, or unitary groups. One family is that of local integrals of the doubling method, and the other family is that of local integrals expressed in terms of sph...
