Quotients, automorphisms and differential operators
Let V be a G-module where G is a complex reductive group. Let Z := V//G denote the categorical quotient and let π : V → Z be the morphism dual to the inclusion O(V ) ⊂ O(V ). Let φ : Z → Z be an algebraic automorphism. Then one can ask if there is an algebraic map Φ: V → V which lifts φ, i.e., π(Φ(v)) = φ(π(v)) for all v ∈ V . In Kuttler [Kut11] the case is treated where V = rg is a multiple of...
متن کاملAutomorphisms of Quotients of Symmetric Groups
We describe the automorphism group of the quotient of the symmetric group on a countably innnite set by the group of nitary permutations. We show that the outer automorphism group is innnite cyclic. In the proof, we examine the structure of centralizers in this quotient.
متن کاملQuotients of `∞(z,z) and Symbolic Covers of Toral Automorphisms
This note gives an account of the algebraic construction of symbolic covers and representations of ergodic automorphisms of compact abelian groups. For expansive toral automorphisms this subject was initiated by A.M. Vershik.
متن کاملViability and generalized differential quotients
Necessary and sufficient conditions for a set-valued map K : R ։ R to be GDQ-differentiable are given. It is shown that K is GDQ differentiable at t0 if and only if it has a local multiselection that is Cellina continuously approximable and Lipschitz at t0. It is also shown that any minimal GDQ of K at (t0, y0) is a subset of the contingent derivative of K at (t0, y0), evaluated at 1. Then this...
متن کاملThe inversion formulae for automorphisms of polynomial algebras and differential operators in prime characteristic
Let K be an arbitrary field of characteristic p > 0, let A be one of the following algebras: Pn := K[x1, . . . , xn] is a polynomial algebra, D(Pn) is the ring of differential operators on Pn, D(Pn) ⊗ Pm, the n’th Weyl algebra An, the n’th Weyl algebra An ⊗ Pm with polynomial coefficients Pm, the power series algebra K[[x1, . . . , xn]], Tk1,...,kn is the subalgebra of D(Pn) generated by Pn and...
