ALGEBRAIC GEOMETRY FROM AN ALGORITHMIC POINT OF VIEW
July 17-21, 2023, Warsaw, Poland
Nowadays, it is well-known that also long-standing open problems in Algebraic Geometry can benefit of algorithmic methods that are developed by Computer Algebra.
The first obvious reason is that algorithms allow the construction of examples, from which researchers can deduce possible solutions to the questions they deal with. In this context, the necessity to design new algorithms for specific topics of interest or to optimize the existing ones often arises. Indeed, several existing algorithms theoretically allow some explicit computations (e.g. Groebner Bases) but in practice they do not give the desired result in a reasonable time, or using a reasonable amount of memory.
The second less obvious reason is that projecting an algorithm can give a new insight in the problem one is trying to solve. On the one hand, the algorithmic approach to a problem gives the chance to prove a statement in a constructive way; on the other hand, the effort needed to obtain a new Computer Algebra tool to tackle an open problem often allows to better enter the mechanism of the problem itself, highlighting new features that could not be seen with an existential approach.
As a consequence of the two above points, investigations in Algebraic Geometry from a computational point of view can also provide applications in other fields (e.g. coding theory, cryptography, computer graphics).
This session aims at gathering specialists from different areas (Algebraic Geometry, Computer Algebra, Applied Mathematics) and discuss interactions between them.
Talks should focus on
algebraic and combinatorial aspects of problems in Algebraic Geometry;
algorithms and constructive methods for Algebraic Geometry and applications;
implementation of algorithms and optimization, possibly with comparisons with existing ones.
