Accurate affiliation matching, which links affiliation strings to standardized organization identifiers, is critical for improving research metadata quality, facilitating comprehen…
Patterns in Shi tableaux and Dyck paths
Myrto Kallipoliti, Robin Sulzgruber, Eleni Tzanaki
Shi tableaux are special binary fillings of certain Young diagrams which arise in the study of Shi hyperplane arrangements related to classical root systems. For type , the set…
Bijections between generalized Catalan families of types A and C
Myrto Kallipoliti, Eleni Tzanaki
Motivated by the relation holding for the m-generalized Catalan numbers of type A and C, the connection between dominant regions of the m-Shi arrangement of type A and C is investi…
Facets of the -generalized cluster complex and regions in the -extended Catalan arrangement of type
Susanna Fishel, Myrto Kallipoliti, Eleni Tzanaki
In this paper we present a bijection between two well known families of Catalan objects: the set of facets of the -generalized cluster complex and the set of do…
A poset fiber theorem for doubly Cohen-Macaulay posets and its applications to non-crossing partitions and injective words
Myrto Kallipoliti, Martina Kubitzke
This paper studies topological properties of the lattices of non-crossing partitions of types A and B and of the poset of injective words. Specifically, it is shown that after the…
The absolute order on the symmetric group, constructible partially ordered sets and Cohen-Macaulay complexes
Christos A. Athanasiadis, Myrto Kallipoliti
The absolute order is a natural partial order on a Coxeter group W. It can be viewed as an analogue of the weak order on W in which the role of the generating set of simple reflect…
