A hypergraph $H = (V,E)$ is said to have K\H{o}nig's Property if there is a matching $M\subseteq E$ and $S\subseteq V$ such that $|S \cap e| = 1$ for all $e\in M$, and $S$ is a vertex cover of $H$. Aharoni posed the question whether K\H{o}nig's Prope

Ron Aharoni and Vladimir Korman conjectured that any hypergraph with only finite edges has a strongly minimal cover. We present a counterexample.

Gr\"atzer and Lakser asked in the 1971 {\sl Transactions of the American Mathematical Society} if the pseudocomplemented distributive lattices in the amalgamation class of the subvariety generated by ${\bf 2}^n\oplus{\bf 1}$ can be characterized by t

Graph embeddings deal with injective maps from a given simple, undirected graph $G=(V,E)$ into a metric space, such as $\mathbb{R}^n$ with the Euclidean metric. This concept is widely studied in computer science, see \cite{ge1}, but also offers attra

For a hypergraph $H=(V,\mathcal E)$, a subfamily $\mathcal C\subseteq \mathcal E$ is called a cover of the hypergraph if $\bigcup\mathcal C=\bigcup\mathcal E$. A cover $\mathcal C$ is called minimal if each cover $\mathcal D\subseteq\mathcal C$ of th

We introduce and examine order convergence and the interval topology on partially ordered sets in general. Problem 76 of Birkhoff's "Lattice Theory" asks whether for complete Boolean algebras the order topology and the interval topology coincide. We
