COAMALGAMATION, CONGRUENCE COEXTENSION AND COTRANSFERABILITY
M. Kianpi and C. Nkuimi-Jugnia
|
Abstract: The properties of transferability, congruence extension, surjectivity of epis and amalgamation are well known in the field of Universal Algebra in the classical setting. A dualization of these properties in the field of general Universal Coalgebra leads to an association of each of the dual properties with a class of weak limits preserving functors. This helps extend some well-known characterizations of these classes of functors. |
Keywords and phrases: coalgebra, weak pullback, coamalgation, cotransferability, congruence coextension, bisimulation, congruence, absolutely closed (open), (co)saturated. |
