我们考虑矢量自旋玻璃,其能量函数是高斯随机场,其协方差以标量乘积矩阵给出。对于此类中的基本上任何模型,我们给出了极限自由能的上限,预计该上限是尖锐的。该界限用无限维 Hamilton-Jacobi 方程表示。
We consider vector spin glasses whose energy function is a Gaussian random field with covariance given in terms of the matrix of scalar products. For essentially any model in this class, we give an upper bound for the limit free energy, which is expected to be sharp. The bound is expressed in terms of an infinite-dimensional Hamilton-Jacobi equation.
