<p>Let $A$ be a positive matrix. What is known about the Birkhoff norm of its Perron vector?</p> <p>By the Birkhoff norm of a vector $x$ I refer to the quantity $\frac{\max{x}}{\min{x}}$.</p> <p>P.S. This is actually a spiced-up restatement of <a href="http://mathoverflow.net/questions/98025/concentration-for-eigenvectors" rel="nofollow">my older question</a>.</p>
