A systematic approach for invariants of C*-algebras
, 2023 We define a categorical framework in which we build a systematic construction that provides generic invariants for C*-algebras. The benefit is significant as we show that any invariant arising this way automatically enjoys nice properties such as ...

Order dense injectivity of $S$-posets [PDF]
Categories and General Algebraic Structures with Applications, 2015 In this paper, the notion of injectivity with respect to order dense embeddings in the category of $S$-posets, posets with a monotone action of a pomonoid $S$ on them, is studied.

Unitary posets and amalgamations of pomonoids
, 2014 In 1927, Schreier proved that amalgams of groups are always embeddable in the category of groups. However, this is not true in the category of semigroups, as shown by Kimura.

On (po-)torsion free and principally weakly (po-)flat $S$-posets [PDF]
Categories and General Algebraic Structures with Applications, 2018 In this paper, we first consider (po-)torsion free and principally weakly (po-)flat $S$-posets, specifically we discuss when (po-)torsion freeness implies principal weak (po-)flatness.

On direct products of S-posets satisfying flatness properties
TURKISH JOURNAL OF MATHEMATICS, 2014 In this paper we characterize pomonoids over which various flatness properties of S-posets are preserved under direct products.

Better-Quasi-Orders: Extensions and Abstractions [PDF]
, 2015 We generalise the notion of -scattered to partial orders and prove that some large classes of -scattered partial orders are better-quasi-ordered under embeddability.

Generalization of Catalan combinatorics to the context of graphs [PDF]
, 2016 Il est question dans le présent document de certaines familles d'objets mathématiques dont la cardinalité se dénombre par la célèbre suite des nombres de Catalan. Nous nous concentrons sur certaines propriétés du treillis de Tamari.

Antisymmetry and the Conservation of C-Command: Scrambling and Phrase Structure in Synchronic and Diachronic Perspective [PDF]
, 2009 Holmberg’s Generalization (Holmberg 1986) was originally stated to describe the “object shift” phenomena found in the modern Scandinavian languages. This dissertation argues that object shift is merely a subcase of scrambling, a type of adjunction, and ...
