Quantum Unipotent Subgroup and Dual Canonical Basis
In a series of works [18, 21, 19, 20, 23, 22], Geiß-Leclerc-Schröer defined the cluster algebra structure on the coordinate ring C[N(w)] of the unipotent subgroup, associated with a Weyl group element w. And they proved cluster monomials are contained in Lusztig’s dual semicanonical basis S∗. We give a set up for the quantization of their results and propose a conjecture which relates the quant...
متن کاملCyclic Orbit Codes with the Normalizer of a Singer Subgroup
An algebraic construction for constant dimension subspace codes is called orbit code. It arises as the orbits under the action of a subgroup of the general linear group on subspaces in an ambient space. In particular orbit codes of a Singer subgroup of the general linear group has investigated recently. In this paper, we consider the normalizer of a Singer subgroup of the general linear group a...
متن کاملTHE CANONICAL SUBGROUP OF E IS SpecR[x]/(x p +
Let p be a prime. In this note we make explicit some results on the canonical subgroup of an elliptic curve E over the ring of integers Rp of Cp implicit in [K-pPMF]. In particular, if ω generates Ω1E/Rp and E has a canonical subgroup CE , knowlege of the Hasse invariant of the reduction of (E,ω) modulo p is equivalent to knowledge of the pair (CE , ω|CE). 1. Group Schemes of order p. Let μ den...
متن کاملDetecting the Index of a Subgroup in the Subgroup Lattice
A theorem by Zacher and Rips states that the finiteness of the index of a subgroup can be described in terms of purely lattice-theoretic concepts. On the other hand, it is clear that if G is a group and H is a subgroup of finite index of G, the index |G : H| cannot be recognized in the lattice L(G) of all subgroups of G, as for instance all groups of prime order have isomorphic subgroup lattice...
متن کاملOn the Cyclic Subgroup Separability of Free Products of Two Groups with Amalgamated Subgroup
Let G be a free product of two groups with amalgamated subgroup, π be either the set of all prime numbers or the one-element set {p} for some prime number p. Denote by Σ the family of all cyclic subgroups of group G, which are separable in the class of all finite π-groups. Obviously, cyclic subgroups of the free factors, which aren’t separable in these factors by the family of all normal subgro...
