One of the ?rst Computer Science sites in Italy, in recent years, the Friuli region has become a very active hub in Computational Physics and other applications of Informatics to Human and Natural Sciences. In particular the University of Udine has developed a tradition in innovative cross-disciplinary research areas involving Computer Science and Physics, providing digital tools for laboratories such as NASA and CERN. The sixth International Symposium "Frontiers of Fundamental and Compu- tional Physics" (FFP6) aimed at providing a platform for a wide range of phy- cists to meet and share thoughts on the latest trends in various research areas including High Energy Physics, Theoretical Physics, Gravitation and Cosmology, Astrophysics, Condensed Matter Physics, Fluid Mechanics. Such frontier lines were uni?ed by the use of computers as an, often primary, research instrument, or dealing with issues related to information theory. The present Sixth International Symposium in the series wasorganizedatthe UniversityofUdine,Italyfrom26thto29th ofSeptember2004. TheUniversity of in the Udine and the B. M. Birla Science Centre in Hyderabad have collaborated organization of this Symposium and the edition of these Proceedings, under the auspices of their joint initiative the International Institute of ApplicableMat- maticsand InformationSciences. ThecontributionsintheProceedingsaregrouped as follows: * Field Theory, Relativity and Cosmology * Foundations of Physics and of Information Sciences * Nuclear and High-Energy Particle Physics and Astrophysics; Astroparticle Physics * Complex Systems; Fluid Mechanics * New Approaches to Physics Teaching ThisSymposiumhadanattendanceofover100participants. Therewere63- pers/presentations, including 4 introductory invited lectures delivered by the - belLaureatesL. CooperandG. 'tHooft,andbytheeminentphysicistsY.

These proceedings contain a selection of refereed papers presented at or related totheAnnualWorkshopoftheTYPESproject(EUcoordinationaction510996), which was held during May 2-5, 2007 in Cividale del Friuli (Udine), Italy. The topic of this workshop was formal reasoning and computer progr- ming basedon type theory: languagesand computerized toolsfor reasoning, and applications in several domains such as analysis of programming languages, c- ti?ed software, formalization of mathematics and mathematics education. The workshopwasattended by morethan 100researchersandincluded morethan 40 presentations. We also had the pleasure of three invited lectures, from Fr ed eric Blanqui (INRIA, Protheo team), Peter Sewell (University of Cambridge) and Amy Felty (University of Ottawa). From 22 submitted papers, 13 were selected after a reviewing process. Each submitted paper was reviewed by three referees; the ?nal decisions were made by the editors. This workshop is the last of a series of meetings of the TYPES working group funded by the European Union (IST project 29001, ESPRIT Working Group 21900, ESPRIT BRA 6435)."

ETAPS 2001 was the fourth instance of the European Joint Conferences on Theory and Practice of Software. ETAPS is an annual federated conference that was established in 1998 by combining a number of existing and new conferences. This year it comprised ve conferences (FOSSACS, FASE, ESOP, CC, TACAS), ten satellite workshops (CMCS, ETI Day, JOSES, LDTA, MMAABS, PFM, RelMiS, UNIGRA, WADT, WTUML), seven invited lectures, a debate, and ten tutorials. The events that comprise ETAPS address various aspects of the system de- lopment process, including speci cation, design, implementation, analysis, and improvement. The languages, methodologies, and tools which support these - tivities are all well within its scope. Di erent blends of theory and practice are represented, with an inclination towards theory with a practical motivation on one hand and soundly-based practice on the other. Many of the issues involved in software design apply to systems in general, including hardware systems, and the emphasis on software is not intended to be exclusive.
