curprev 03:0003:00, 10 July 2024 JamesTheBane talk contribs m 39,431 bytes +100 Add "citation needed" tag for the claim that the function associated with an algebraic groupoid can be partial. MathWorld, for example, appears to state that the function must be total: "The first type of groupoid is an algebraic structure on a set with a binary operator. The only restriction on the operator is closure (i.e., applying the binary operator to two elements of a given set S returns a value which is itself a member of S)." undo
