Resumo: In this talk, we quickly recall the concept of atoms from Katzarkov-Kontsevich-Pantev-Yu. This Gromov-Witten-based construction recently led to new birational invariants. We explain how this idea can be generalized to produce birational invariants for stacks and G-birational invariants for smooth projective varieties with regular G-actions. This talk is based on ongoing joint work with L. Grama, L. Katzarkov, and M. Kontsevich.
