关于SK模型配分拆函数多项式矩的注记
A note on the polynomial moments of the partition function in the SK model
摘要:
证明了SK模型中分拆函数$Z_N(\cdot)$的$k$阶矩与分拆函数$Z_k(\cdot)$的$N$阶矩之间的一个简单恒等式.作为一个推论,我们发现一个表征的极限$\lim_{N \to \infty} \frac{1}{N} \log \mathbb{E} Z_N(β)^k$替代米歇尔Talagrand以前发现的\cite{4}。
英文摘要:
We prove a simple identity relating the $k$th moment of the partition function $Z_N(\cdot)$ in the SK model to the $N$th moment of the partition function $Z_k(\cdot)$. As a corollary we find a characterisation of the limit $\lim_{N \to \infty} \frac{1}{N} \log \mathbb{E} Z_N(β)^k$ alternative to the one found previously by Michel Talagrand in \cite{4}.
