Counting problems are among the oldest in algebraic geometry, and many techniques and tools, such as intersection theory, Schubert calculus, moduli theory etc. were developed to find answers to these questions. In the past few decades, the introduction of new ideas from physics, representation theory, derived categories, derived algebraic geometry and logarithmic geometry among others have revolutionized the field of enumerative geometry. The aim of this workshop is to bring together experts to discuss new and exciting developments in enumerative geometry, Gromov-Witten theory, Donaldson-Thomas theory, and related areas.
