The series of Static Analysis s- posia has served as the primary venue for presentation and discussion of th- retical, practical, and application advances in the area. This volume contains the papers accepted for presentation at the 10th - ternational Static Analysis Symposium (SAS 2003),which was held June 11–13, 2003 in San Diego, California, USA. Firmly established as a leading forum in the static analysis area, SAS 2003 received 82 high-quality submissions. Each paper was carefully reviewed, being judgedaccordingtoscienti?cquality,originality,andrelevancetothesymposium topics. Following on-line discussions, the program committee met in Paris, France, ́ at the Ecole Normale Sup ́ erieure on March 15, 2003, and selected 25 papers. In addition to the contributed papers, this volume includes an invited paper by Manuel Hermenegildo (Technical University of Madrid and University of New Mexico)and the abstractof aninvited talk by KenMcMillan (Cadence Berkeley Laboratories). On behalf of the Program Committee and the General Chair, I would like to thank the authors of the submitted papers, and the external referees, who p- vided timely and signi?cant reviews. I owe special thanks to Jacques Beigbeder ́ from Ecole Normale Sup ́ erieure for managing the submission site and the dev- opers of CyberChair for the use of their software. On this occasion, SAS was sponsored by the Association for Computing - chinery(ACM) andwasheld aspartofthe FederatedComputing ResearchC- ference (FCRC 2003). I would like to thank all organizing committee members for all their tremendous work.

This book constitutes the thoroughly refereed revised selected papers of the 13th International Symposium on Trends in Functional Programming, TFP 2012, held in St Andrews, Scotland, UK in June 2012. The 18 revised full papers included in this volume were carefully and selected from 49 submissions and are complemented with an invited paper. They cover various aspects of trends in functional programming.

This book constitutes the thoroughly refereed post-conference proceedings of the 23rd International Symposium on Implementation and Application of Functional Languages, IFL 2011, held in Lawrence, Kansas, USA, in October 2011. The 11 revised full papers presented were carefully reviewed and selected from 33 submissions. The papers by researchers and practitioners who are actively engaged in the implementation and the use of functional and function based programming languages describe practical and theoretical work as well as applications and tools. They discuss new ideas and concepts, as well as work in progress and results.
