The nineteenth MEGA conference 2026 will take place in Durham, UK, during the period July 6 - July 10, 2026. The meeting is hosted by Durham University, United Kingdom.

The webpage of the conference can be found at https://maths.dur.ac.uk/mega2026/

MEGA is the acronym for Effective Methods in Algebraic Geometry (and its equivalent in Italian, French, Spanish, German, Russian, etc.). This series of biennial international conferences, which began in 1990, is devoted to computational and application aspects of Algebraic Geometry and related topics.  The permanent webpage of the MEGA conferences is at https://mega.sciencesconf.org/.

MEGA conferences have emerged from the leading research activity in Effective Algebraic Geometry developed in Europe over the last decades. They have established themselves as an important vehicle in the exploration of the broad interactions between Algebraic Geometry and Computational and Applied domains of Mathematics. The conferences have also increasingly been attracting young talented researchers, showing the strength and vitality of the community. The MEGA conferences aim at promoting the development of the subject through academic exchange between international researchers, at presenting the recent progress of the domain through the presentation of selected talks, at updating the community knowledge through the invitation of talented researchers from Europe and outside, and at attracting and supporting young students and researchers to join the current research area.

----------------Contributed Presentations----------------

Submissions of papers/extended abstracts are open and available at EasyChair.

Deadline for submissions of papers/extended abstracts: 1 December 2025

Notification of acceptance of papers/extended abstracts: 1 March 2026

Deadline for submission of computation presentations/posters: 15 March 2026

Notification of acceptance of computation presentations/posters: 1 April 2026

Submissions should contain recent original research relevant to effective methods in algebraic geometry (in a broad sense), including their foundations, analysis, complexity, computational aspects, practical issues, and applications.

There are three types of submissions, distributed over the two deadlines above:

• Regular papers, aimed to contributed talks: for these, authors can choose to submit either an extended abstract of at least six pages (not counting bibliography) that should contain full results, an outline of the proofs and all of the main ideas; or else a full paper with complete proofs.
• Computation presentations: these can concern new software packages, but also experiments with existing software that have led to new computational approaches to mathematical proofs/applications relevant to MEGA. Submission should be in the form of a short paper describing the software or computations.
• Posters: to be printed on A1, the posters will be exhibited during most of the conference, and during a poster session the authors will have the opportunity to discuss their work with the conference participants.

All submissions should clearly state the contributions and achievements, with sufficient detail to understand their significance. Submissions may contain material already submitted elsewhere, but this fact has to be stated explicitly in the abstract. Acceptance of a submitted contribution means acceptance for oral or poster presentation only. A special issue of a journal is planned. Authors of accepted original papers will be invited to submit the full version after the conference. Only original research contributions will be considered for publication in the journal special issue. We particularly encourage the participation of young researchers.
