Around the tangent cone theorem
A cornerstone of the theory of cohomology jump loci is the Tangent Cone theorem, which relates the behavior around the origin of the characteristic and resonance varieties of a space. We revisit this theorem, in both the algebraic setting provided by cdga models, and in the topological setting provided by fundamental groups and cohomology rings. The general theory is illustrated with several cl...
متن کاملTangent cone algorithm for homogenized differential operators
We extend Mora’s tangent cone or the écart division algorithm to a homogenized ring of differential operators. This allows us to compute standard bases of modules over the ring of analytic differential operators with respect to sufficiently general orderings which are needed in the D-module theory.
متن کاملThe Tangent Cones at Double points of Prym-Canonical Divisors of Curves of genus 7
Let η be a line bundle on a smooth curve X with η^2=0 such that π_η, the double covering induced by η is an etale morphism. Assume also that X_η be the Prym-canonical model of X associated to K_X.η and Q is a rank 4 quadric containing X_η. After stablishing the projective normality of the prym-canonical models of curves X with Clifford index 2, we obtain in this paper a sufficient condition for...
متن کاملRelative Bogomolov’s Inequality and the Cone of Positive Divisors on the Moduli Space of Stable Curves
Throughout this paper, we fix an algebraically closed field k. Let f : X → Y be a surjective and projective morphism of quasi-projective varieties over k with dim f = 1. Let E be a vector bundle of rank r on X . Then, we define the discriminant divisor of E with respect to f : X → Y to be disX/Y (E) = f∗ (( 2rc2(E)− (r − 1)c1(E) ) ∩ [X ]) . Here f∗ is the push-forward of cycles, so that disX/Y ...
متن کاملCurves in the Lightlike Cone
In this paper, we study curves in the lightlike cone. We first obtain the conformally invariant arc length in the (n+1)-dimensional lightlike cone and then characterize some curves in the 2-dimensional lightlike cone and 3-dimensional lightlike cone. MSC 2000: 53A04, 53A30, 53B30
