提出了一个关于二分结构平均场自旋玻璃极限的猜想,并证明了该极限是一个上界。约束极限是用一个无限维Hamilton-Jacobi方程的解来描述的。这个问题的一个基本困难是这个方程中的非线性不是凸的。我们还质疑的可能性来描述这个约束极限的鞍点问题。
We propose a conjecture for the limit of mean-field spin glasses with a bipartite structure, and show that the conjectured limit is an upper bound. The conjectured limit is described in terms of the solution of an infinite-dimensional Hamilton-Jacobi equation. A fundamental difficulty of the problem is that the nonlinearity in this equation is not convex. We also question the possibility to characterize this conjectured limit in terms of a saddle-point problem.
