This book is issued from a conference around resurgent functions in Physics and multiple
zetavalues which was held at the Centro di Ricerca Matematica Ennio de Giorgi in Pisa on May
18-22 2015. This meeting originally stemmed from the impressive upsurge of interest for Jean
Ecalle's alien calculus in Physics in the last years - a trend that has considerably developed
since then. The volume contains both original research papers and surveys by leading experts
in the field reflecting the themes that were tackled at this event: Stokes phenomenon and
resurgence in various mathematical and physical contexts but also related constructions in
algebraic combinatorics and results concerning numbers specifically multiple zetavalues.
