### Chapter 1. Whitney Stratifications

Abstract
A (smooth) manifold (i.e., a C-manifold without boundary, of constant dimension) enjoys the next well-known homogeneity property, see, for instance, [M4], p. 22.

### Chapter 2. Links of Curve and Surface Singularities

Abstract
We start with a brief account of knot theory for the following two reasons. First, the links of (plane) curve singularities—which are usually regarded as the simplest class of singularities to investigate—form a special class of knots, the so-called algebraic links. Second, many of the fundamental concepts related to the local topology of a higher dimensional IHS (e.g., Seifert matrix, intersection form, Milnor fibration, Alexander polynomial) have been considered first in relation to knot theory.

### Chapter 3. The Milnor Fibration and the Milnor Lattice

Abstract
In this section we introduce various Milnor fibrations, in particular, the global Milnor fibration associated with a weighted homogeneous polynomial. Then we discuss the basic properties of the corresponding monodromy operators. Let On+1 = ℂ{x0,…,xn{ be the ℂ-algebra of analytic function germs at the origin 0 of ℂn+1 and let (X, 0) be a hypersurface singularity defined by an equation f = 0, for some fOn+1 with f(0) = 0. Here n ≥ 0 is a positive integer. There are two equivalent fibrations which, in the literature, are called the Milnor fibration of the function germ f (or of the hypersurface singularity (X, 0)).

### Chapter 4. Fundamental Groups of Hypersurface Complements

Abstract
We have seen in Chapter 2 that a basic idea in studying a link LS3 is to investigate the topology of its complement S3\L. In particular, the fundamental group π1(S3\L) of this space played a crucial role. Note that since most of the spaces of interest to us are path-connected, we usually pay no attention to base points.

### Chapter 5. Projective Complete Intersections

Abstract
Although the topology of the complex projective space ℙn is well known, we recall in this section some basic facts on it. The reason for doing this is:
(i)
to fix some notation useful in the sequel; and

(ii)
the topology of the projective complete intersections shares a lot of properties with the topology of ℙn.

### Chapter 6. de Rham Cohomology of Hypersurface Complements

Abstract
In this chapter we work with regular differential forms in the sense of Algebraic Geometry or, depending on the context, in the sense of Analytic Geometry. Fix a positive integer n ≥ 0 and consider the affine space ℂn+1.
