随机矩阵与随机置换

Random Matrices and Random Permutations

Andrei Okounkov

摘要:

我们证明了Baik,Deift和Johansson的猜想,它说,相对于Plancherel措施的一组分区的$n$,第1,第2,等等,行的行为,适当的规模,像第1,第2,等等,特征值的高斯随机埃尔米特矩阵作为$n$走向无穷大。我们的证明是基于表面上的地图和分歧覆盖的领域之间的相互作用。我们还建立了这个问题与曲线的模空间上的相交理论的联系。

英文摘要:

We prove the conjecture of Baik, Deift, and Johansson which says that with respect to the Plancherel measure on the set of partitions of $n$, the 1st, 2nd, and so on, rows behave, suitably scaled, like the 1st, 2nd, and so on, eigenvalues of a Gaussian random Hermitian matrix as $n$ goes to infinity. Our proof is based on an interplay between maps on surfaces and ramified coverings of the sphere. We also establish a connection of this problem with intersection theory on the moduli spaces of curves.
