Impossibility results on stability of phylogenetic consensus methods
Emanuele Delucchi, Linard Hoessly, Giovanni Paolini
We answer two questions raised by Bryant, Francis and Steel in their work on consensus methods in phylogenetics. Consensus methods apply to every practical instance where it is des…
Orlik-Solomon-type presentations for the cohomology algebra of toric arrangements
Filippo Callegaro, Michele D'Adderio, Emanuele Delucchi +2
We give an explicit presentation for the integral cohomology ring of the complement of any arrangement of level sets of characters in a complex torus (alias "toric arrangement"). O…
Stanley-Reisner rings for symmetric simplicial complexes, G-semimatroids and Abelian arrangements
Alessio D'Alì, Emanuele Delucchi
We extend the notion of face rings of simplicial complexes and simplicial posets to the case of finite-length (possibly infinite) simplicial posets with a group action. The action…
