Intervals in partial monounary algebras

Danica Jakubíková-Studenovská (1991)

Mathematica Bohemica

Similarity:

In this paper the notion of an interval in a partial monounary algebra is introduced and pairs $(A, f)$ , $(A, g)$ of partial monounary algebras are investigated such that each interval in $(A, f)$ is also an interval in $(A, g)$ , and conversely.

Two types of retract irreducibility of connected monounary algebras

Danica Jakubíková-Studenovská (1996)

Mathematica Bohemica

Similarity:

Let $𝒜$ be a connected monounary algebra. The paper deals with retract irreducibility of $𝒜$ in the class of all connected monounary algebras and in the class of all monounary algebras.
