Completeness of Unary Coalgebras
by
Ewa Graczynska
Technical University of Opole, Poland
Our aim is to present some application of universal algebra methods for the theory of coalgebras of a given cotype.
In particular, we invent coterms and M-cohyperidentities.
We present a slight modification of Birkhoff's type variety theorem of H. P. Gumm.
A completeness theorem for M-cohypervarieties will be dicussed.
