摘要:
Berezin-Karpelevich积分是酉矩阵上的二重积分,在矩形矩阵模型中起着Itzykson-Zuber积分的作用。我们以单调Hurwitz数给出了Berezin-Karpelevich积分的拓扑展开,并由此得到某些组合恒等式。
英文摘要:
The Berezin-Karpelevich integral is a double integral over unitary matrices which plays the role of the Itzykson-Zuber integral in rectangular matrix models. We obtain a topological expansion of the Berezin-Karpelevich integral in terms of monotone Hurwitz numbers, and obtain from this certain combinatorial identities.
