It is evident that for any class . of .-ary multirelations either . or its complement is induced, and also that any finite intersection of induced classes is an induced clas

Carolin Holzmeier,Natalie Mayerl relation, on the base |R|. The relation S is in a sense “in general position” relative to R. For example, if R is the chain of natural numbers and . = 1, the unary general relation S is + for infinitely many numbers and — for infinitely many numbers; S is + for infinitely many even numbers and — f

Local Isomorphism and Logical Formula; Logical Restriction Theorem,Let R and R′ be two multirelations with bases E and E′ respectively, and . a local isomorphism of R onto R′ defined on a subset F ⊆ E and mapping it onto some F′⊆ E′ (see Volume 1,4.1). We associate with . certain pairs of integers (., .), defined recursively as follows.
