The Largest Subsemilattices of the Endomorphism Monoid of an Independence Algebra

João Araújo, Wolfram Bentz, Janusz Konieczny

An algebra $\A$ is said to be an independence algebra if it is a matroid algebra and every map $\al:X\to A$, defined on a basis $X$ of $\A$, can be extended to an endomorphism of $…
