Multidimensional Residues and Tropical Geometry (June 14–18, 2021, Sochi)
The goal of this workshop is a comprehensive discussion of currently interesting topics of complex analysis in several variables and its applications. We give special attention to multidimensional residues, integral representations and their applications to description of structure of discriminantal sets, domains of convergence of the MellinBarnes integrals, problems of invariant theory, theory of motives, and differential operators theory. We plan to discuss also problems of the pluripotential theory and its relations to the theory of supercurrents and tropical geometry, recent advances in the CRgeometry and the problem of description of real hypersurfaces in complex manifolds; multidimesional aspects of approximation and interpolation, as well as related problems of algebraic geometry, singularity theory, and mathematical physics.
