  • Characterization of clones of boolean operations by identities 
    Butkote, R.; Denecke, K. (Algebra and Discrete Mathematics, 2007)
    In [4] the authors characterized all clones of Boolean operations (Boolean clones) by functional terms. In this paper we consider a Galois connection between operations and equations and characterize all Boolean clones ...
  • Clones of full terms 
    Denecke, K.; Jampachon, P. (Algebra and Discrete Mathematics, 2004)
    In this paper the well-known connection between hyperidentities of an algebra and identities satisfied by the clone of this algebra is studied in a restricted setting, that of n-ary full hyperidentities and identities ...
  • Green’s relations on the seminearring of full hypersubstitutions of type (n) 
    Changphas, Th.; Denecke, K. (Algebra and Discrete Mathematics, 2003)
    Hypersubstitutions are mappings which are used to define hyperidentities and solid varieties. In this paper we will show that the set of all hypersubstitutions of a given type forms a seminearring. We will give a full ...
