Let $V$ be a degree $d$, reduced hypersurface in $\mathbb{CP}^{n+1}$, $n \geq 1$, and fix a generic hyperplane, $H$. Denote by $\mathcal{U}$ the (affine) hypersurface complement, $\mathbb{CP}^{n+1}-V \cup H$, and let $\mathcal{U}^c$ be the infinite cyclic covering of $\mathcal{U}$ corresponding to the kernel of the total linking number homomorphism. Using intersection homology theory, we give a new construction of the Alexander modules $H_i(\mathcal{U}^c;\mathbb{Q})$ of the hypersurface… 
On Betti Numbers of Milnor Fiber of Hyperplane Arrangements
Let $\mathcal{A}$ be a central hyperplane arrangement in $\mathbb{C}^{n+1}$ and $H_i,i=1,2,...,d$ be the defining equations of the hyperplanes of $\mathcal{A}$. Let $f=\prod_i H_i$. There is a global

Let $$n>0$$n>0 and $$f: {\mathbb {C}}^{n+1}\rightarrow {\mathbb {C}}$$f:Cn+1→C be a reduced polynomial map, with $$D=f^{-1}(0)$$D=f-1(0), $${\mathcal {U}}={\mathbb {C}}^{n+1}{\setminus } D$$U=Cn+1\D
The monodromy theorem for compact Kähler manifolds and smooth quasi-projective varieties
Given any connected topological space X, assume that there exists an epimorphism $$\phi {:}\; \pi _1(X) \rightarrow {\mathbb {Z}}$$ϕ:π1(X)→Z. The deck transformation group $${\mathbb {Z}}$$Z acts on
Higher-order Alexander Invariants of Hypersurface Complements
We define the higher-order Alexander modules $A_{n,i}(\mathcal{U})$ and higher-order degrees $\delta_{n,i}(\mathcal{U})$ which are invariants of a complex hypersurface complement $\mathcal{U}$. These
Reidemeister torsion, peripheral complex and Alexander polynomials of hypersurface complements
Let $f:\CN \rightarrow \C $ be a polynomial, which is transversal (or regular) at infinity. Let $\U=\CN\setminus f^{-1}(0)$ be the corresponding affine hypersurface complement. By using the
L2-Betti Numbers of Hypersurface Complements
In \cite{DJL07} it was shown that if $\scra$ is an affine hyperplane arrangement in $\C^n$, then at most one of the $L^2$--Betti numbers $b_i^{(2)}(\C^n\sm \scra,\id)$ is non--zero. In this note we
Motivic zeta functions and infinite cyclic covers
We associate with an infinite cyclic cover of a punctured neighborhood of a simple normal crossing divisor on a complex quasi-projective manifold (assuming certain finiteness conditions are

Eigenspace Decomposition of Mixed Hodge Structures on Alexander Modules
In previous work jointly with Geske, Maxim and Wang, we constructed a mixed Hodge structure (MHS) on the torsion part of Alexander modules, which generalizes the MHS on the cohomology of the Milnor


Hypersurface Complements, Alexander Modules and Monodromy
We consider an arbitrary polynomial map $f:{\mathbb C}^{n+1}\to {\mathbb C} $ and we study the Alexander invariants of ${\mathbb C}^{n+1}\setminus X$ for any fiber $X$ of $f$. The article has two
Homotopy groups of the complements to singular hypersurfaces, II
The homotopy group $\pi_{n-k} ({\bf C}^{n+1}-V)$ where $V$ is a hypersurface with a singular locus of dimension $k$ and good behavior at infinity is described using generic pencils. This is analogous
Milnor fibers and higher homotopy groups of arrangements
We describe a new relation between the topology of hypersurface complements, Milnor fibers and degree of gradient mappings. In particular we show that any projective hypersurface has affine parts
Singular spaces, characteristic classes, and intersection homology

Intersection homology II
In [19, 20] we introduced topological invariants IH~,(X) called intersection homology groups for the study of singular spaces X. These groups depend on the choice of a perversity p: a perversity is a

Singularities and Topology of Hypersurfaces
This book systematically presents a large number of basic results on the topology of complex algebraic varieties using the information on the local topology and geometry of a singularity. These
