Abstract This is a book about graph homomorphisms, intended to introduce this exciting topic to a wide audience. It attempts to bring together what the authors see as the highlights of the theory and its many applications, and could be read as a sampler of this rich theory, and its most interesting results, techniques, and ...

Homomorphisms and promotability
1989The construction of structure-preserving maps, or “homomorphisms,” is described for an arbitrary data type: examples of these functions are given for list- and tree-like structures and types defined by mutual induction. From the definition of a data type it is also possible to infer a “promotion” theorem for proving equalities of homomorphisms.

Derivations as Homomorphisms or Anti-homomorphisms on Lie Ideals
Acta Mathematica Sinica, English Series, 2006The authors show that if a derivation \(D\) of a prime ring \(R\) with \(\text{char\,}R\neq 2\), acts like a (anti-) homomorphism on a noncentral Lie ideal of \(R\), then \(D=0\).

Stores as homomorphisms and their transformations
1993We address the problem of giving a clean and uniform mathematical model for handling user-defined data types in imperative languages, contrary to the ad hoc treatment usual in classical denotational semantics. The problem is solved by defining the store as a homomorphic mapping of an algebraic structure of left values modelling containers into another ...
