Local residues in $\mathbf C^n$. Algebraic applications
A. K. Tsikh
Abstract:
Connected with a ingular point $a$ of an algebraic set $V=\{z\in\mathbf C^n:g(z)=0\}$ is the local residue
\begin{equation}
\operatorname{res}\limits_{\Gamma_a}(f/g)=\int_{\Gamma_a}\frac{f(z)}{g(z)}\,dz,
\end{equation}
of the rational function $f/g$, where $\Gamma_a$ is a cycle which has a representative in the $n$-dimensional homology group $H_n(\mathbf C^n\setminus V)$ in every neighborhood of the point $a$. The structure of the local residues of the form (1) is described in the case of an isolated singular point $a$: they are expressed in terms of finitely many derivatives of $f$ at $a$. As an application of local residues a theorem of Noether and Bertini is generalized to any number of variables.
