α-diperfect digraphs

Anais do III Encontro de Teoria da Computação (ETC 2018), 2018
Let D be a digraph. A path partition P of D is a collection of paths such that {V(P) : P ∈ P} is a partition of V(D). We say D is α-diperfect if for every maximum stable set S of D there exists a path partition P of D such that |S ∩ V (P )| = 1 for all P ∈ P and this property holds for every induced subdigraph of D.

Species on Digraphs

Advances in Mathematics, 1996
The author applies the language of Joyal's species to enumeration problems of digraphs using the machinery of coloured species, see, e.g., the author and \textit{O. Nava} [J. Comb. Theory, Ser. A 64, No. 1, 102-129 (1993; Zbl 0787.05095)]. A species over digraphs is defined as a functor from the category of digraphs to the category of finite sets and ...

Finite-dimensional flexible algebras associated with directed and weighted CW complexes

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
In this paper, we study a link between directed and weighted CW complexes (also called configurations) and flexible algebras determining which configurations are associated with those algebras.
