Abstract:
A (central) arrangement $\A$ is a finite family of one codimensional subspaces of a vector space $V$. Relations between the module of logarithmic forms of $\A$ and the module of logarithmic forms of $\A \setminus \{ H \}$ are studied. It is found that the logarithmic $q$-forms of $\A$ are generated by the logarithmic forms of the type ${d α } \over α $ if $\A$ is $k$-generic and $q \leq k-2$.
