关于闭半代数集上半代数函数的拓扑

On the topology of semi-algebraic functions on closed semi-algebraic sets

Nicolas Dutertre

摘要:

考虑定义在闭半代数集X上的半代数函数。我们给出了X的拓扑与函数的临界点的指数和函数在无穷远处的拓扑行为的关系式。当X是R^n且函数是线性的时,我们给出了应用。

英文摘要:

We consider a semi-algebraic function defined on a closed semi-algebraic set X. We give formulas relating the topology of X to the indices of the critical points of the function and to the topological behavior of the function at infinity. We give applications when X is R^n and when the function is linear.
