We consider function fields of functions of one variable augmented by the binary operation of composition of functions. It is shown that the straightforward axiom
The Nested List Normal Form is proposed as a syntactic normal form for semantically well-designed database schemata obtained from any arbitrary finite nesting of records and lists....
The class composition C K of Boolean clones, being the set of composite functions f(g1, . . . , gn) with f C, g1, . . . , gn K, is investigated. This composition C K is either...
Reasoning about preferences is a major issue in many decision making problems. Recently, a new logic for handling preferences, called Qualitative Choice Logic (QCL), was presented...
