Resumen de Relative Calabi–Yau structures II: shifted Lagrangians in the moduli of objects

Christopher Brav, Tobias Dyckerhoff

  • We show that a Calabi–Yau structure of dimension d on a smooth dg category C induces a symplectic form of degree 2−d on ‘the moduli space of objects’ MC. We show moreover that a relative Calabi–Yau structure on a dg functor C→D compatible with the absolute Calabi–Yau structure on C induces a Lagrangian structure on the corresponding map of moduli MD→MC.
