Resumen:
The determination of the abundance of heavy elements (e.g. O, N, S, Ar) in gaseous nebulae is fundamental to understand the formation and the chemical evolution of galaxies and of the Universe.Despite recent surveys (e.g. Califa, Sloan Digital Sky Survey) have provided advances in the knowledge of gaseous nebulae and their host galaxies, important aspects in the study of these objectsremain ill-defined. In particular, the abundance discrepancy problem in HII regions and planetary nebulae, generally interpreted as being caused by the presence of temperature fluctuation, callinginto question the nebular abundance scale of the Milk Way and extragalactic objects. In order to address this problem this workshop brought together a group of scientists and students to stimulateextensive discussions about crucial questions related to the study of the chemical abundances in gaseous nebulae.The present volume contains the set of contributions presented at the workshop.
