This issue of EPJST contains a set of 11 articles aiming to put in perspective recent developments in the area of renormalons and hyperasymptotics in QCD. Conceptual problems and phenomenological applications of renormalons are reviewed, based on perturbative calculations, lattice QCD, and mathematical ideas from transseries and resurgence theory.
