定向聚合物与量子Toda晶格

Directed polymers and the quantum Toda lattice

Neil O'Connell

摘要:

利用与量子Toda晶格相关的扩散过程刻画了布朗定向聚合物模型的分拆函数的规律。证明是通过多维推广的一个定理的Matsumoto和Yor关于指数泛函的布朗运动。它是基于一个映射,可以被视为一个几何变体的RSK对应。

英文摘要:

We characterize the law of the partition function of a Brownian directed polymer model in terms of a diffusion process associated with the quantum Toda lattice. The proof is via a multidimensional generalization of a theorem of Matsumoto and Yor concerning exponential functionals of Brownian motion. It is based on a mapping which can be regarded as a geometric variant of the RSK correspondence.
