Ordered Response Models for Sovereign Debt Ratings [PDF]

open access: yes
Using ordered logit and probit plus random effects ordered probit approaches, we study the determinants of sovereign debt ratings. We found that the last procedure is the best for panel data as it takes into account the additional cross-section error ...

On the Structure of Balanced Residuated Partially Ordered Monoids

open access: yes
A residuated poset is a structure $\langle A,\le,\cdot,\backslash,/,1 \rangle$ where $\langle A,\le \rangle$ is a poset and $\langle A,\cdot,1 \rangle$ is a monoid such that the residuation law $x\cdot y\le z\iff x\le z/y\iff y\le x\backslash z$ holds. A residuated poset is balanced if it satisfies the identity $x\backslash x \approx x/x$.

Remark on the identities of the grammic monoid with three generators

open access: yes, 2022
Grammic monoids have recently been introduced by Christian Choffrut in terms of the action of the free monoid over a fixed ordered alphabet $X$ on the set of rows of Young tableaux filled with elements from $X$ via Schensted's insertion. For $X=\{a,b,c\}$

Monoid and Topological Groupoid

open access: yes, 2018
<p>Here we introduce some new results which are relative to the concept of topological monoid-groupoid and prove that the category of topological monoid coverings of X is equivalent to the category covering groupoids of the monoid-groupoid <span

Monoid Based Semantics for Linear Formulas

open access: yes, 2002
Each Girard quantale (i.e. commutative quantale with a selected dualizing element) provides a support for a semantics for linear propositional formulas (but not for linear derivations). Several constructions of Girard quantales are known.

The factorizable braid monoid

open access: yes, 2006
In this paper we study the factorizable braid monoid (also known as the merge-and-part braid monoid) introduced by Easdown, East and FitzGerald in 2004. We find several presentations of this monoid, and uncover an interesting connection with the singular

A class of inverse monoids acting on ordered forests

open access: yesJournal of Algebra, 2004
A ``graph of inverse monoids'' \(\mathbf X\) consists of a connected graph \(Y\) and, for each vertex and each edge of \(Y\) a monoid, together with monomorphisms linking those monoids in a certain fashion. Its fundamental inverse monoid \(\pi_1(\mathbf X)\) is defined here in two ways, one by reference to a specific vertex, the other by reference to a

Cournot–Nash equilibria in continuum games with non-ordered preferences. [PDF]

open access: yes
In the usual framework of continuum games with externalities, we substantially generalize Cournot–Nash existence results [Balder, A unifying approach to existence of Nash equilibria, Int.
