infinity-permutation representation

Context

Higher algebra

(,1)(\infty,1)-Category theory

Contents

Idea

An ∞-representation on objects of ∞Grpd.

The analog on (∞,1)-category theory of a permutation representation.

Properties

Tannaka duality

See at Tannaka duality the section For ∞-permutation representations.

Grothendieck construction

By the (∞,1)-Grothendieck construction \infty-permutation representations

BGGrpd \mathbf{B}G \to \infty \mathrm{Grpd}

correspond to ∞-functors

V//GBG V//G \to \mathbf{B}G

sitting in fiber sequences

VV//GBG, V \to V//G \to \mathbf{B}G \,,

where V//GV//G is the corresponding action ∞-groupoid?.
