摘要：
Given a partial (resp. a global) action Α of a connected finite groupoid G on a ring A, we determine necessary and sufficient conditions for the partial (resp. the global) skew groupoid ring A⋆ ΑG to be a separable extension of A. © 2017, Instituto de Matemática e Estatística da Universidade de São Paulo.
