approximate stationary distributions of a doubly stochastic matrix and its supports
Is it obvious what is meant by "the Birkhoff decomposition" in this question? Because the decomposition of a doubly stochastic matrix into permutation matrices is not necessarily unique. So is your question "for all decompositions ..." or "does there exist a decomposition such that ..."? |

Iwasawa logarithm and analytic continuation
Thanks. Is there any notion of singularity or complete analytic function at all? For example one could take the the polynomial $y^2 - x$ and (as far as I can tell) use Hensel's lemma to expand a power series $p(x) = \sum c_i (x-\alpha)^i$ around every point $\alpha \in \mathbb{C}_p - \{0\}$, in fact, a pair of power series, such that $(x,p(x))$ is identically zero on $y^2 - x$ It seems reasonable to assume that such power series bear some relationship to each other, that an arbitrary pair of power series do not. |

Concentration bounds for sums of random variables of permutations
Thanks, I didn't think about exchangeability when I considered the problem. |

Thanks, I think that set of notes is exactly the sort of thing I was looking for. |
