Foreword
From January to July 2014, the Research Programme Central Configurations,
Periodic Orbits and beyond in Celestial Mechanics took place at the Centre
de Recerca Matemàtica (CRM), in Bellaterra, Barcelona. It was coordinated by
Montserrat Corbera (Universidad de Vic, Spain), Josep Maria Cors (Universitat
Politècnica de Catalunya, Spain), and Jaume Llibre (Universitat Autònoma de
Barcelona,Spain).
Duringtheseintensesevenmonths,severalscientificeventstookplace,including
an international conference (the HAMSYS-2014), three advanced courses, and a
weekly seminar, all of them with the active participation of many visitors invited
toattendfromseveralcountriesabroad.Ofcourse,additionally,allparticipantshad
numerousoccasionstohostinformalbutfruitfulconversationsamongthemselves,
discussingmathematicalideaswhich,inmanycases,gaverisetonewandinterest-
ingresults;altogetherinaverydynamicandproductiveresearchatmosphere.
In this volume of the subseries Research Perspectives CRM-Barcelona (pub-
lished by Birkhäuser inside the series Trends in Mathematics), we present fifteen
Extended Abstracts corresponding to selected talks given by participants in the
Research Programme.More than half of them come from talks at the Conference
onHamiltonianSystemsandCelestialMechanics2014(HAMSYS2014)(heldfrom
June 2nd to 6th, 2014), and the rest come from talks at the weekly seminar held
along the first semester of 2014. We hope the presentation of this material under
the present Extended Abstract form will give to the authors the opportunity to

We would like to expressourgratitudeto CRM forhostingandsupportingour
researchprogramme.AlsoourwarmthankstotheCRMstaff,itsdirector,Joaquim
Bruna, and all the secretaries for providing great facilities and a very pleasant
workingenvironment.Finally,thanksareduetoallthosewhoattendedthetalks,for
theirinterest,theiractiveparticipation,andtheirenthusiasmtowardsmathematics.
