%0 Journal Article %T The two dimensional distribution of values of $¦Æ(1+it)$ %A Youness Lamzouri %J Mathematics %D 2008 %I arXiv %X We prove several results on the distribution function of $\zeta(1+it)$ in the complex plane, that is the joint distribution function of $\arg\zeta(1+it)$ and $|\zeta(1+it)|$. Similar results are also given for $L(1,\chi)$ (as $\chi$ varies over non-principal characters modulo a large prime $q$). %U http://arxiv.org/abs/0801.3692v2
