Grothendieck classes and Chern classes of hyperplane arrangements [PDF]
We show that the characteristic polynomial of a hyperplane arrangement can be recovered from the class in the Grothendieck group of varieties of the complement of the arrangement.

Chern classes and projective geometry [PDF]
Classical projective geometry is rich in relations between the extrinsic invariants (e.g., order, double tangents, number of nodes, triple points, •) associated with an algebraic map /: M —• CPN of a projective algebraic manifold M. It has also long been known that these extrinsic invariants may be sometimes used to define birational or intrinsic ...

On a naturality of Chern-Mather classes [PDF]
Let \(X\) denote a possibly singular algebraic variety and \({\mathcal F}(x)\) the group of constructible functions on \(X\). \textit{R. D. MacPherson} [Ann. Math. (2) 100, 423-432 (1974; Zbl 0311.14001)] showed the existence of a unique natural transformation \(C_*:{\mathcal F}\to H_*\) such that for \(X\) nonsingular \(C_*(\mathbf{1}_X)=c(Tx)\cap [X]\

Profinite Chern classes for group representations [PDF]
Let \(\rho\) : \(G\to GL_ n{\mathbb{C}}\) be a complex representation of the discrete group G. There is an obvious action of field automorphisms of \({\mathbb{C}}\) on the vector bundles of the form \(\xi\) (\(\rho)\), and it is our ojective to study the behavior of Chern classes under this action.

On the positivity of the first Chern class of an Ulrich vector bundle [PDF]
We study the positivity of the first Chern class of a rank [Formula: see text] Ulrich vector bundle [Formula: see text] on a smooth [Formula: see text]-dimensional variety [Formula: see text].

Chern Class Inequalities on Polarized Manifolds and Nef Vector Bundles [PDF]
This article is concerned with Chern class and Chern number inequalities on polarized manifolds and nef vector bundles. For a polarized pair $(M,L)$ with $L$ very ample, our 1st main result is a family of sharp Chern class inequalities.

On the Cohomology Chern Classes of the K-Theory Chern Classes [PDF]
Let ξ \xi be a vector bundle over a finite complex and γ i ξ {\gamma ^i}\xi its i i th- K K theory Chern class. We first show that \[ c n
