A complete presentation of $(\mathbb{C}\mbox{[X]},\circ)$

We recall the fundamental theorem of J.F. Ritt, with a stress on the action of the affine group and canonical forms of complex polynomials. Then we give a complete presentation of the monoid $(\mathbb{C}\mbox{[X]},\circ)$. A list of decomposable polynomials is given in degrees $\leq 12$.

Restricted configuration spaces

Finitely many hypersurfaces are removed from unordered configuration spaces of $n$ points in $\mathbb{C}$ to obtain a fibration over unordered configuration spaces of $n-1$ complex points. Fundamental groups of these restricted configuration spaces are computed in small dimensions.
