Résume

Donaldson--Thomas theory provides a virtual counting of coherent sheaves over complex Calabi–Yau 3-folds. From the deformation-theoretic perspective, DT invariants are shadow of derived critical locus structures.  As a first step toward developing Donaldson–Thomas theory in positive characteristic, I study an enhanced notion of shifted symplectic structure using Antieau’s derived infinitesimal cohomology.
