Effective methods in algebraic geometry 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.

Effective Methods and Theoretical and Practical Complexity Issues in: Commutative Algebra, Geometry, Real Geometry, Algebraic Number Theory, Algebraic Geometry and related fields: Algebraic Analysis of Differential Equations, Differential Geometry, Associative Algebras, Group Theory, Algebraic Groups and Lie Algebras, Algebraic and Differential Topology, as well as applications of these fields.

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), 2003 (Kaiserslautern, Germany), 2005 (Porto Conte, Italy), 2007 (Strobl, Austria), and 2009 (Barcelona, Spain), 2011 (Stockholm, Sweden), 2013 (Frankfurt, Germany) and 2015 (Trento, Italy). 2017 (Nice, France), 2019 (Madrid, Spain).

The next conference MEGA 2021 is planned  inTromso, Norway, June 7-11. The conference homepage can be found here.
