Completeness criteria and invariants for operation and transformation algebrasDanica Jakubíková-Studenovská, Dragan Masulovic and Reinhard PöschelKatedra geometrie a algebry, Prírodovedecká fakulta UPJ{\v S}, Ko\v sice, Slovakia; Institute of Mathematics, University of Novy Sad, Yugoslavia; Institute of Algebra, TU Dresden, GermanyAbstract: \def{\pair}[2]{( Operation algebras serve as representations of composition algebras (in the sense of Lausch/Nöbauer). In this paper they are described and characterized by invariant relations as Galois-closed sets w.r.t.\ a suitable Galois connection. Further, the completeness problem in operation algebras is considered and solved for concrete cases (e.g. for transformation $\pair\max\circ$-semirings).
