From quantum electrodynamics to posets of planar binary trees
Frédéric Chapoton, Alessandra Frabetti
This paper is a brief mathematical excursion which starts from quantum electrodynamics and leads to the Moebius function of the Tamari lattice of planar binary trees, within the fr…
The categorified Diassociative cooperad
Frédéric Chapoton
Using representations of quivers of type A, we define an anticyclic cooperad in the category of triangulated categories, which is a categorification of the linear dual of the Diass…
A rooted-trees q-series lifting a one-parameter family of Lie idempotents
Frédéric Chapoton
We define and study a series indexed by rooted trees and with coefficients in Q(q). We show that it is related to a family of Lie idempotents. We prove that this series is a q-defo…
Shoikhet's Conjecture and Duflo Isomorphism on (Co)Invariants
Damien Calaque, Carlo A. Rossi
In this paper we prove a conjecture of B. Shoikhet. This conjecture states that the tangent isomorphism on homology, between the Poisson homology associated to a Poisson structure…
