چکیده
Milnor’s fibration theorem in [19, 20] states that if (R, 0) f → (R, 0) is the germ of a real analytic map with an isolated critical point at the origin, then for every sufficiently small sphere Sε = ∂Bε around 0 ∈ R n+k one has that the complement Sε \K of the link K = f(0) ∩ Sε fibres over the circle S . The proof of this result is by noticing first that for δ > 0 sufficiently small the tube f(Sδ) ∩ Bε fibres over the circle S 1 δ ⊂ C of radius δ, and then constructing a vector field that ”inflates” this tube taking it into the complement of (a regular neighbourhood of) the link in the sphere. When the map f is from C into C and is holomorphic, Milnor shows that one actually has a much richer structure:

Milnor fibration and fibred links at infinity
Let f : C −→ C be a polynomial function. By definition c ∈ C is a regular value at infinity if there exists a disc D centred at c and a compact set C of C such that the map f : f(D) \ C −→ D is a locally trivial fibration. There are only a finite number of critical (or irregular) values at infinity. For c ∈ C and a sufficiently large real number R, the link at infinity Kc = f (c) ∩ S R is well-...
متن کاملA ug 2 00 2 Homotopy and homology of fibred spaces
We study fibred spaces with fibres in a structure category F and we show that cellular approximation, Blakers–Massey theorem, Whitehead theorems, obstruction theory, Hurewicz homomorphism, Wall finiteness obstruction, and Whitehead torsion theorem hold for fibred spaces. For this we introduce the cohomology of fibred spaces. AMS SC : 55R55 (Fiberings with singularities); 54H15 (Transformation g...
متن کاملبررسی شکافتگی کوچک و دیگر تکینگیهای آینده عالم و برقراری قانون دوم ترمودینامیک در نظریه
The future singularities are possible in a universe that is described by F(R) theory. In previous studies the occurrence of the singularities in F(R) theory have been considered by using a special function for the Hubble parameter and calculating the F(R) function for each of the singularities. Using the specified Hubble parameter causes some difficulties in the study of the second law of therm...
متن کاملCompatible Contact Structures of Fibered Seifert Links in Homology 3-spheres
We introduce a new technique for constructing contact structures compatible with fibered Seifert multilinks in homology 3-spheres and fibered multilinks with cabling structures in any 3-manifolds. The contact structure constructed in this paper is so well-organized that we can easily see if it is tight or overtwisted in most cases. As an application, we classify the tightness of contact structu...
متن کاملA sharp bound for the slope of double cover fibrations
Let f : X → B be a fibred surface of genus g whose general fibre is a double cover of a smooth curve of genus γ. We show that, for g > 4γ+1, 4 g−1 g−γ is a sharp lower bound for the slope of f , proving a conjecture of Barja. Moreover, we give a characterisation of the fibred surfaces that reach the bound. In the case g = 4γ+1 we obtain the same sharp bound under the assumption that the involut...
