Loop Space Models and Integral Homology of Connected Quandles

Abstract

We construct a marked integral delooping of a connected quandle's covering monoid, realizing its rack space as a homotopy fiber. For finite connected quandles at primes p not dividing a point-stabilizer order, we determine the local A∞ type and the ordinary rack cohomology shuffle algebra over fields of characteristic p. We compute integral quandle homology in all positive degrees for finite connected regular cyclic Alexander quandles and the tetrahedral quandle. At such primes dividing the quandle order, rack-space homotopy groups have exponentially many cyclic direct summands of fixed p-power order in each sufficiently large degree.
