Šlapal, Josef
On strong regularity of relations. (English). Mathematica Bohemica, vol. 119 (1994), issue 2, pp. 151-155
MSC: 03E20, 04A05, 08A02 | MR 1293248 | Zbl 0807.04001 | DOI: 10.21136/MB.1994.126076
Keywords:
relations of type $\alpha$; reflexivity; diagonality; strong regularity; homomorphism; extended preorders
Summary:
There exists a natural extension of the notion of preorder from binary relations onto relations whose arities are arbitrary ordinals. In the article we find a condition under which extended preorders coincide with preorders if viewed categorically.
