Rewriting in Free Hypergraph Categories [PDF]
We study rewriting for equational theories in the context of symmetric monoidal categories where there is a separable Frobenius monoid on each object. These categories, also called hypergraph categories, are increasingly relevant: Frobenius structures ...

Gcd-monoids arising from homotopy groupoids [PDF]
The interval monoid $\Upsilon$(P) of a poset P is defined by generators [x, y], where x $\le$ y in P , and relations [x, x] = 1, [x, z] = [x, y] $\times$ [y, z] for x $\le$ y $\le$ z.

On a complete topological inverse polycyclic monoid
We give sufficient conditions when a topological inverse $\lambda$-polycyclic monoid $P_{\lambda}$ is absolutely $H$-closed in the class of topological inverse semigroups.

Syntactic Monoids in a Category [PDF]
The syntactic monoid of a language is generalized to the level of a symmetric monoidal closed category D. This allows for a uniform treatment of several notions of syntactic algebras known in the literature, including the syntactic monoids of Rabin and ...

The \v Cerný conjecture for aperiodic automata [PDF]
A word w is called a synchronizing (recurrent, reset, directable) word of a deterministic finite automaton (DFA) if w brings all states of the automaton to some specific state; a DFA that has a synchronizing word is said to be synchronizable.

Resolutions for free partially commutative monoids [PDF]
A free resolution of free partially commutative monoids is constructed and with its help the homological dimension of these monoids is calculated.

The Largest Subsemilattices of the Endomorphism Monoid of an Independence Algebra [PDF]
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 $\A$.

Measuring cones and other thick subsets in free groups [PDF]
In this paper we investigate the special automata over finite rank free groups and estimate asymptotic characteristics of sets they accept. We show how one can decompose an arbitrary regular subset of a finite rank free group into disjoint union of ...

Explicit left orders on free groups extending the lexicographic order on free monoids [PDF]
For every finitely generated free group we construct an explicit left order extending the lexicographic order on the free monoid generated by the positive letters. The order is defined by a left, free action on the orbit of 0 of a free group of piecewise
