Baslik: On the topology of real analytic maps

Özet: In this talk we describe a vibration theorem for real analytic maps
$f:\mathbb{R}^n\to\mathbb{R}^p$ with arbitrary singularities. Now suppose
that $f$ satisfies Thom's property with respect to a Whitney stratification
and let $g:\mathbb{R}^n\to\mathbb{R}^k$ be another real analytic map with
isolated singularity at the origin in the stratified sense. We give a
Le-Greuel type formula which relates the Euler-Poincaré characteristic of
the fibres of $f$ and $(f,g)$.

When $f$ and $(f,g)$ are isolated complete intersections we construct an
integer valued invariant called the curvature integra which gives the Euler
characteristic of the fibres.

Saygilarimla
