An explicit description of the second cohomology group of a quandle
We use the inflation-restriction sequence and a result of Etingof and Graña on the rack cohomology to give a explicit description of 2-cocycles of finite indecomposable quandles with values in an abelian group. Several applications are given. © 2016, Springer-Verlag Berlin Heidelberg.
