Ključne reči: partitions of type n; (n + 1)-ary equivalence relation
Sažetak
(ne postoji na srpskom)
The notation of a partition of type n, (n Є N), was introduced by J. Hartmanis in [1] as a generalization of the notion of an ordinary partition of a set. It is well-known fact that partitions Q (of type 1) correspond in an one-one way to equivalence relations on Q. In this article we introduce an analogous family of relations (Fn(Q)) for partitions of type n. Furthermore for p Є Fn(Q) the following statements hold: ○ (n+1 p) = p and (n p) - 1 = p for n = 1: ~ ○ ~ = ~ and ~ (cf. [3]). A similar family of relations for partitions of type n was described by H.E. Pickett in [2] point out the differences.
