First Announcement MEGA 2005 The Eight International Symposium on Effective Methods in Algebraic Geometry Computing _in_ and _with_ algebraic geometry: Theory, Algorithms, Implementations, Applications. Porto Conte, Alghero, Sardinia (Italy) May 26th -- June 2nd MEGA is the acronym for Effective Methods in Algebraic Geometry (and its equivalent in Italian, French, Spanish, German, Russian, etc.), a series of roughly biennial conferences on computational and application aspects of Algebraic Geometry and related topics with very high standards. Previous meetings were held in 1990 (Castiglioncello, Italy), 1992 (Nice, France), 1994 (Santander, Spain),1996 (Eindhoven, Nederlands), 1998 (St. Malo, France) 2000 (Bath, United Kingdom) and 2003 (Kaiserslautern, Germany). Proceedings containing a selection of the papers and invited talks presented at previous Mega conferences have been published by Birkh\"auser in the series Progress in Mathematics (volumes no. 94, 109 and 143), by the Journal of Pure and Applied Algebra (volumes no. 117 and 118, 139 and 164) and by the Journal of Symbolic Computation (to appear). We plan to do the same for MEGA 2005, the details will be contained in the first call. Conference chair Carlo Traverso, Pisa Conference Committee Alicia Dickenstein (Buenos Aires, Argentina), Andr\'e Galligo (Nice, France), Patrizia Gianni (Pisa, Italy), Marc Giusti (Palaiseau, France), Teo Mora (Genova, Italy), Tomas Recio (Santander, Spain), Joseph Schicho (Linz, Austria). Advisory Board The MEGA conference series is led since 1990 by an advisory board, that guarantees the continuity and the quality of the conferences. The board is stable, but small changes are performed at every issue; the board for 2005, for which we expect to have small changes with respect to the board for MEGA 2003, will be announced later.

Alghero has an international airport, served bylow-cost airlines, and connected to Milano, Roma, London, Hahn-Frankfurt and Girona-Barcelona. Another possible airport is Olbia. People coming with a car can come through Porto Torres, 35km far, with daily ferry connections from Marseille and Genova. Registration and Accomodation A registration form will be available online on the Mega WWW-site from March 2005 on. The registration fee will be approximately 150 Euro per person (110 Euro for accompanying persons, 60 Euro for students; 50 Euro supplement for late registration). It will partly cover the conference expenses. Precise details and electronic forms will be posted later. Submissions Papers should be submitted electronically by January 7, 2003. The details will be contained in the second announcement, expected at the beginning of September 2004.
