Recent Trends in Tropical Geometry

tbranzov2026-04-30T11:36:11+03:00April 30th, 2026|Conferences, Topological, Computational, and Algebraic Aspects of Complex Systems|

What new structures emerge when algebraic varieties degenerate to piecewise-linear shadows? How do tropical curves illuminate enumerative invariants and mirror symmetry? Where does tropical geometry meet non-archimedean analysis, symplectic topology, and the geometry of moduli? Recent Trends in Tropical Geometry is a research conference bringing together a focused group of mathematicians working in tropical geometry and its interactions with algebraic geometry, enumerative geometry, mirror symmetry, non-archimedean geometry, and related areas.

This conference is the first in a series of conferences dedicated to the Theory of Atoms, established through the proven collaboration of the ICMS, IHES, IMSA, and UNICAMP consortium. The next conferences will take place in Miami (IMSA) and Brazil (UNICAMP, IMPA). Sponsors: Simons Foundation, National Science Foundation, University of Miami, and Bulgarian Ministry of Education and Science. The event is jointly organized by the Research Group on Theory of Atoms, hosted at the International Centre for Mathematical Sciences (ICMS-Sofia) at the Institute of Mathematics and Informatics, Bulgarian Academy of Sciences, and the Institute for the Mathematical Sciences of the Americas (IMSA) at the University of Miami.

tbranzov2025-12-09T12:21:56+02:00November 3rd, 2025|Conferences, Topological, Computational, and Algebraic Aspects of Complex Systems|

The workshop brings together a focused group of researchers working across non-Kähler complex geometry, Hodge-theoretic and categorical structures, quantum and irregular phenomena, and mirror symmetry. The goal is to clarify and refine a set of ideas that appear as “atomic” components across these areas, and to create space for concentrated discussion and collaboration. The program combines extended sessions, research talks, and blackboard discussions. The setting is intended to be mathematically rigorous, collegial, and oriented toward identifying new structures and open directions.

Sandpiles and Tropical Geometry, Specialized PhD Course

tbranzov2025-10-22T11:47:18+03:00October 22nd, 2025|Topological, Computational, and Algebraic Aspects of Complex Systems|

This course examines the intersection of Abelian Sandpile Theory and Tropical Geometry—two frameworks revealing how discrete local rules generate global geometric order. Offered by the Topological and Geometric Complexity Group at ICMS Sofia, the course welcomes doctoral students and researchers interested in the geometric foundations of complex systems.
