Estructuras A-infinito en la opérada de cactus
(2012)
Comunicació de congrés
Accés restringit per política de l'editorialDiversas versiones de la opérada de cactus inicialmente definida por Voronov han sido estudiadas. Es conocida su equivalencia débil con la opérada de pequeños discos. Se conoce pues que la opérada de cactus admite una ... -
Linkages, the topology of the polygon space and Walker’s conjecture
(Universitat Politècnica de Catalunya, 2020-07)
Projecte Final de Màster Oficial
Accés obertThis thesis aims to introduce the notions of linkage and its confguration space, that can be motivated as a model that describes the motion of mechanical linkages. We focus on cyclic linkages that give place to the polygon ... -
Monoidal functors, acyclic models and chain operads
(2004)
Article
Accés obertWe prove that for a topological operad P the operad of oriented cubical chains, Cord ¤ (P), and the operad of singular chains, S¤(P), are weakly equivalent. As a consequence, Cord ¤ (P;Q) is formal if and only if S¤(P;Q) ... -
Reeb embeddings and universality of Euler flows
(Springer, 2021)
Capítol de llibre
Accés obertWe use a new geometrical approach to the universality of Euler flows. By proving flexibility results on embeddings for Reeb flows in contact topology, we deduce some new universal properties for Euler flows. As a byproduct, ... -
Regularisation in ejection-collision orbits of the RTBP
(2018)
Text en actes de congrés
Accés obertNumerical explorations confirm well-known analytical results on the ex-istence of ejection-collision orbits in the restricted three-body problem for veryrestrictive values of the Jacobi constantC. For different values ... -
The Berkovits complex and semi-free extensions of Koszul algebras
(2015-08-18)
Report de recerca
Accés obertIn his extension of W. Siegel's ideas on string quantization, N. Berkovits made several observations which deserve further study and development. Indeed, interesting accounts of this work have already appeared in the ... -

Three Hopf algebras and their common simplicial and categorical background
(2016-07)
Report de recerca
Accés obertWe consider three a priori totally different setups for Hopf algebras from number theory, mathematical physics and algebraic topology. These are the Hopf algebras of Goncharov for multiple zeta values, that of Connes--Kreimer ... -
