The CRM’s forthcoming programme ”Follow-Up of the Research Programme: INTERACTIONS BETWEEN REPRESENTATION THEORY, ALGEBRAIC TOPOLOGY AND COMMUTATIVE ALGEBRA (IRTATCA)” (http:/www.crm.cat/2019/FU_IRTATCA) is scheduled from June 3rd to 15th, 2019 – Barcelona, Spain.

The CRM and IMUB are pleased to announce the follow-up programme for the “IRTATCA: Interactions between Representation Theory, Algebraic Topology and Commutative Algebra” intensive research programme that was held in 2015 at the CRM. The programme and its follow-up are devoted to promote interactions between researchers from different areas that share a common interest in homological techniques in a broad sense. The original programme gathered around 200 researchers from all over the world, and it is now time to have a look at some of the progress that took place since then.

These two weeks will be structured around one Advanced Course between the 3rd and 7th of June 2019, that will take place at the IMUB and a Conference between the 11th and the 15th of June 2019 that will take place at the CRM.

Topics:

The programme is open to all researchers interested in homological algebra and its applications in areas like commutative algebra, representation theory and algebraic topology. This includes but is not restricted to: the study of triangulated categories derived algebraic geometry, homotopy theory, singularity theory, representation theory, etc.

During the Research Programme the following activities will be held:

- Advanced Course:

Crossing Cohomological bridges

(triangulated categories, singularity theory and 2-Segal spaces)

Ideals, Varieties, Applications

https://iva2019.wordpress.amherst.edu/

This is a conference to honor David Cox and his influence in several areas of Commutative Algebra and Algebraic Geometry, on occasion of his forthcoming retirement in the summer of 2019.

The theory and computation of Gröbner bases has grown to become an indispensable component of research in algebraic geometry and commutative algebra. Gröbner bases are used to develop intuition with explicit examples, to test conjectures, and in some cases to help create proofs. Gröbner techniques continue to make inroads in a range of applications, e.g. in computer vision , statistics and systems biology. Gröbner bases are available in excellent free software packages, such as Macaulay 2, COCOA, Singular, and Sage, as well as in commercial algebra systems, such as Magma and Maple.

This conference will bring together graduate students and researchers at all levels to survey the state of the art in computational and combinatorial algebraic geometry. A special emphasis will be placed on illustrating how computation of Gröbner bases drives both theory and applications. In particular, speakers will cover advances in algorithms, toric varieties, Cox rings, syzygies, tropical algebraic geometry, geometric modeling, and applications to computer-aided-design (CAD).
