Resumen:
Let $pi in mathbb S_m$ be a product of disjoint cycles of the same length, $mathcal C$ the conjugacy class of $pi$ and $rho$ an irreducible representation of the centralizer of $pi$. Weprove that either the Nichols algebra $mathfrak B (mathcal C,rho)$ is infinite-dimensional, or the braiding of the Yetter-Drinfeld module is negative.
