永久性的界限和一些应用

Bounds on the permanent and some applications

Leonid Gurvits, Alex Samorodnitsky

摘要:

给出了双随机阵的积和式的新的上界。结合以前的工作,这提高了永久的确定性近似因子。我们也给出了一个组合应用的下界,证明了S。Friedland的“渐近下匹配猜想”的单体-二聚体问题。

英文摘要:

We give new lower and upper bounds on the permanent of a doubly stochastic matrix. Combined with previous work, this improves on the deterministic approximation factor for the permanent. We also give a combinatorial application of the lower bound, proving S. Friedland's "Asymptotic Lower Matching Conjecture" for the monomer-dimer problem.
