We show that the absolute numerical index of the space $L_p(\mu)$ is $p^{-1/p} q^{-1/q}$ (where $1/p+1/q=1$). In other words, we prove that $$ \sup\{\int |x|^{p-1}|Tx|\, d\mu \, : \ x\in L_p(\mu),\,\|...

In order to find explicit numerical approximation of K¨ahler-Einstein metric of projective manifolds, Donaldson introduced in [3] various operators with good properties to approximate classical operat...
