Discrepancy formula for derived blow-ups
Discrepancy formula for derived blow-ups
Assume the setting of the derived blow-up over , with morphism and integer as in the main theorem. Let and be the cotangent complexes of and over . Discrepancy conjecture. There is an isomorphism
This conjecture proposes a relationship between virtual codimension and discrepancy in derived birational geometry. In the stated setting, it is known when , is a derived scheme, and both and are smooth, as well as when the derived blow-up is smooth; the general case remains open.
