ON THE REAL MILNOR FIBRE OF SOME MAPS FROM Rn TO R2

چکیده
We consider a real analytic map-germ (f, g) : (R, 0) → (R, 0). Under some conditions, we establish degree formulas for the following quantities : χ({f = α} ∩ {g = δ} ∩B ε ), χ({f = α} ∩ {g ≥ δ} ∩B ε )− χ({f = α} ∩ {g ≤ δ} ∩B ε ), where (α, δ) is a regular value of (f, g) and 0 < |(α, δ)| ¿ ε ¿ 1.

Curvature Integrals on the Real Milnor Fibre
Let f : Rn+1 → R be a polynomial with an isolated critical point at 0 and let ft : Rn+1 → R be a one-parameter deformation of f . We study the differential geometry of the real Milnor fiber Cε t = f −1 t (0) ∩ B n+1 ε . More precisely, we express the following limits : lim ε→0 lim t→0 1 εk ∫ Cε t sn−k(x) dx, where sn−k is the (n− k)-th symmetric function of curvature, in terms of the following ...
متن کاملStratified critical points on the real Milnor fibre and integral-geometric formulas
Let (X, 0) ⊂ (R, 0) be the germ of a closed subanalytic set and let f and g : (X, 0) → (R, 0) be two subanalytic functions. Under some conditions, we relate the critical points of g on the real Milnor fibre X ∩ f(δ)∩Bǫ, 0 < |δ| ≪ ǫ ≪ 1, to the topology of this fibre and other related subanalytic sets. As an application, when g is a generic linear function, we obtain an “asymptotic” Gauss-Bonnet...
متن کاملVanishing Cycles in Complex Symplectic Geometry
We study the vanishing cycles on the Milnor fibre for some non-isolated singularities which appear naturally in symplectic geometry. Under assumptions given in the text, we show that the vanishing cycles associated to a distinguish basis freely generate the corresponding homology groups of the Milnor fibre. We derive some consequences of this fact, in particular for the study of adjoint orbits ...
متن کاملM ay 2 00 9 Monotonicity of entropy for real multimodal maps ∗
In [16], Milnor posed the Monotonicity Conjecture that the set of parameters within a family of real multimodal polynomial interval maps, for which the topological entropy is constant, is connected. This conjecture was proved for quadratic by Milnor & Thurston [17] and for cubic maps by Milnor & Tresser, see [18] and also [5]. In this paper we will prove the general case.
