摘要：We confirm the quasi-projective case of Saito's conjecture (Invent. Math. 207:597-695, 2017), namely that the cohomological characteristic classes defined by Abbes and Saito can be computed in terms of the characteristic cycles. We construct a cohomological characteristic class supported on the non-acyclicity locus of a separated morphism relatively to a constructible sheaf. As applications of the functorial properties of this class, we prove cohomological analogs of the Milnor formula and the...

摘要：In this paper we prove a higher dimensional analogue of Carleson's epsilon 2 conjecture. Given two arbitrary disjoint Borel sets Omega(+),Omega(-)subset of Rn+1, and x is an element of Rn+1, r>0, we denote epsilon(n)(x,r):=1/r(n) inf(H+)H(n)(((partial derivative B(x,r)boolean AND H+)\Omega(+))boolean OR((partial derivative B(x,r)boolean AND H-)\Omega(-))), where the infimum is taken over all open affine half-spaces H+ such that x is an element of partial derivative H+ and we define H-=Rn+1\H+....

摘要：We give an alternative proof of the Schoen-Simon-Yau curvature estimates and associated Bernstein-type theorems (Schoen et al. in Acta Math. 134:275-288, 1975), and extend the original result by including the case of 6-dimensional (stable minimal) immersions. The key step is an epsilon-regularity theorem, that assumes smallness of the scale-invariant L2\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepack...
