The conference will be devoted to toric topology, toric geometry, and adjacent areas, such as homotopy theory, Hamiltonian actions on symplectic manifolds, combinatorics, discrete and convex geometry. Toric topology is an area of active research, which brought together powerful ideas from various fields of mathematics. This subject studies group actions on manifolds and varieties, mainly torus actions (either actions of compact tori on smooth manifolds, or actions of algebraic tori on varieties) from the viewpoint of the underlying combinatorial structures: polytopes, fans, and simplicial complexes.
The aim of the conference is twofold. First, we want to gather researchers in toric topology, so that they can share their latest scientific ideas and strengthen the existing collaborations. Second, we want to invite new people to tell about their research, making valuable contributions to the subject area.
