Formulas for Multiplier Ideals on Singular Varieties
نویسنده
چکیده
We prove a generalization of Demailly-Ein-Lazarsfeld’s subadditivity formula [DEL] and Mustaţǎ’s summation formula [Mu] for multiplier ideals to the case of singular varieties, using characteristic p methods. As an application of our formula, we improve Hochster-Huneke’s result [HH4] on the growth of symbolic powers of ideals in singular affine algebras.

When Does the Subadditivity Theorem for Multiplier Ideals Hold?
Demailly, Ein and Lazarsfeld [DEL] proved the subadditivity theorem for multiplier ideals, which states the multiplier ideal of the product of ideals is contained in the product of the individual multiplier ideals, on non-singular varieties. We prove that, in two-dimensional case, the subadditivity theorem holds on log-terminal singularities. However, in higher dimensional case, we have several...
متن کاملDiscreteness and Rationality of F -jumping Numbers on Singular Varieties
We prove that the F -jumping numbers of the test ideal τ(X ; ∆, a) are discrete and rational under the assumptions that X is a normal and F -finite variety over a field of positive characteristic p, KX + ∆ is Q-Cartier of index not divisible p, and either X is essentially of finite type over a field or the sheaf of ideals a is locally principal. This is the largest generality for which discrete...

متن کاملLog geometry and multiplier ideals
I work in combinatorics, algebraic geometry, convex geometry and commutative algebra while staying informed on certain topics in category theory and ring theory. In particular, I focus on toric varieties and singularity theory. The study of toric varieties lies at the intersection of combinatorics, algebraic geometry, convex geometry and integer programming. There is a correspondence between ce...
متن کاملComputations of Multiplier Ideals via Bernstein-sato Polynomials
Multiplier ideals are very important in higher dimensional geometry to study the singularities of ideal sheaves. It reflects the singularities of the ideal sheaves and provides strong vanishing theorem called the Kawamata-Viehweg-Nadel vanishing theorem (see [3]). However, the multiplier ideals are defined via a log resolution of the ideal sheaf and divisors on the resolved space, and it is dif...
