Homomorphisms of heterogeneous algebras

Miroslav Novotný (2002)

Czechoslovak Mathematical Journal

Similarity:

A construction of all homomorphisms of a heterogeneous algebra into an algebra of the same type is presented. A relational structure is assigned to any heterogeneous algebra, and homomorphisms between these relational structures make it possible to construct homomorphisms between heterogeneous algebras. Homomorphisms of relational structures can be constructed using homomorphisms of algebras that are described in [11].

Transferral of entailment in duality theory II: strong dualisability

Maria João Gouveia, Miroslav Haviar (2011)

Czechoslovak Mathematical Journal

Similarity:

Results saying how to transfer the entailment in certain minimal and maximal ways and how to transfer strong dualisability between two different finite generators of a quasi-variety of algebras are presented. A new proof for a well-known result in the theory of natural dualities which says that strong dualisability of a quasi-variety is independent of the generating algebra is derived.
