Subalgebra extensions of partial monounary algebras

Danica Jakubíková-Studenovská (2006)

Czechoslovak Mathematical Journal

Similarity:

For a subalgebra $ℬ$ of a partial monounary algebra $𝒜$ we define the quotient partial monounary algebra $𝒜 / ℬ$ . Let $ℬ$ , $𝒞$ be partial monounary algebras. In this paper we give a construction of all partial monounary algebras $𝒜$ such that $ℬ$ is a subalgebra of $𝒜$ and $𝒞 ≅ 𝒜 / ℬ$ .

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.
