Motivic integration and Milnor fiber

چکیده

We put forward a uniform narrative that weaves together several variants of Hrushovski– Kazhdan style integral, and describe how it can facilitate the understanding Denef–Loeser motivic Milnor fiber closely related objects. Our study focuses on so-called “nonarchimedean fiber” was introduced by Hrushovski Loeser, our thesis is richer embodiment underlying philosophy construction. The said first developed in more natural complex environment, then extended to real one via descent. In process doing so, we are able provide illuminating new proofs, free resolution singularities, few pivotal results literature, both real. To begin with, zeta function shown be rational, which yields fiber; this an analogue Hrushovski–Loeser Then, applying $T$-convex integration after descent, matching Euler characteristics topological becomes matter simple computation, not only singularities as proof, but also other sophisticated algebro-geometric machineries. Finally, establish, much intuitive manner, Thom–Sebastiani formula, specialized given Guibert–Loeser–Merle.

Motivic Serre Invariants, Ramification, and the Analytic Milnor Fiber

where s is a complex variable, f is a polynomial over Zp in n variables, |f | is its p-adic norm, and |dx| denotes the Haar measure on the compact group Zp , normalized to give Zp measure 1. A priori, Zp(f, s) is only defined when R(s) > 0. However, Igusa proved, using resolution of singularities, that it has a meromorphic continuation to the complex plane. Moreover, it is a rational function i...

Motivic Milnor Fibre of Cyclic L∞-algebras

We define motivic Milnor fibre of cyclic L∞-algebras of dimension three using the method of Denef and Loeser of motivic integration. It is proved by Nicaise and Sebag that the topological Euler characteristic of the motivic Milnor fiber is equal to the Euler characteristic of the étale cohomology of the analytic Milnor fiber. We prove that the value of Behrend function on the germ moduli space ...

Constructible motivic functions and motivic integration

1.1. In this paper, intended to be the first in a series, we lay new general foundations for motivic integration and give answers to some important issues in the subject. Since its creation by Maxim Kontsevich [23], motivic integration developed quickly and has spread out in many directions. In a nutshell, in motivic integration, numbers are replaced by geometric objects, like virtual varieties...

Motivic interpretation of Milnor K-groups attached to Jacobian varieties

In the paper [Som90] p.105, Somekawa conjectures that his Milnor Kgroup K(k, G1, . . . , Gr) attached to semi-abelian varieties G1,. . . ,Gr over a field k is isomorphic to ExtrMk (Z, G1[−1] ⊗ . . . ⊗ Gr[−1]) where Mk is a certain category of motives over k. The purpose of this note is to give remarks on this conjecture, when we take Mk as Voevodsky’s category of motives DM (k) .

Arc Spaces , Motivic Integration

The concept ofmotivic integrationwas invented by Kontsevich to show that birationally equivalent Calabi-Yau manifolds have the same Hodge numbers. He constructed a certain measure on the arc space of an algebraic variety, the motivic measure, with the subtle and crucial property that it takes values not in R, but in the Grothendieck ring of algebraic varieties. A whole theory on this subject wa...
