Borel morphism

(Definition)

|
Definition 0.1 Let $\grp_B$ and $\grp_B$ * be two groupoids whose object spaces are Borel. An algebraic morphism from $\grp_B$ to $\grp_B$ * is defined as a left action of $\grp_B$ on $\grp_B$ * which commutes with the multiplication on $\grp_B$ . Such an algebraic morphism between Borel groupoids is said to be a Borel morphism if the action of $\grp_B$ on $\grp_B$ * is Borel ( viz. ref. [ 1])
