Abstract:

We show that for $p\geq 1$ and $r\geq 1$ the $p$-th moment of the $\ell _r$-norm of a log-concave random vector is comparable to the sum of the first moment and the weak $p$-th moment up to a constant proportional to $r$. This extends the previous result of Paouris concerning Euclidean norms.
