Log Canonical Thresholds and Generalized Eckardt Points

چکیده
Let X be a smooth hypersurface of degree n ≥ 3 in P. We prove that the log canonical threshold of H ∈ |−KX| is at least n−1 n . Under the assumption of the Log minimal model program, we also prove that a hyperplane section H of X is a cone in P over a smooth hypersurface of degree n in P if and only if the log canonical threshold of H is n−1 n .

Log Canonical Thresholds of Binomial Ideals
We prove that the log canonical thresholds of a large class of binomial ideals, such as complete intersection binomial ideals and the defining ideals of space monomial curves, are computable by linear programming.

متن کاملGeneralized Eckardt Points.
All varieties are assumed to be projective and defined over a field of characteristic 0, unless mentioned. Main definitions and notations appear in [KMM] and [Sh93]. Classically, an Eckardt point is a point on a nonsingular cubic surface Σ at which three lines on this surface intersect each other. In other words, it is a point p on Σ such that there is an element in | − KΣ| which is a cone with...
متن کاملLog Canonical Threshold, Segre Classes, and Polygamma Functions
We express the Segre class of a monomial scheme in projective space in terms of log canonical thresholds of associated ideals. Explicit instances of the relation amount to identities involving the classical polygamma functions.
متن کامل2 00 3 on F - Pure Thresholds
Using the Frobenius map, we introduce a new invariant of a pair (R, a) of a ring R and an ideal a ⊂ R, which we call the F-pure threshold c(a) of a, and study its properties. We see that the F-pure threshold characterizes some ring theoretic properties. By virtue of Hara and Yoshida's result [HY], the F-pure threshold c(a) in characteristic zero corresponds to the log canonical threshold lc(a) ...
