Abstract

We introduce a mathematical framework based on simple combinatorial arguments (Kernel Representation) that allows to deal successfully with spin glass problems, among others. Let ΩN\Omega^{N} be the space of configurations of an NN- spins system, each spin having a finite set Ω\Omega of inner states, and let μ:ΩN[0,1]\mu:\Omega^{N}\rightarrow\left[0,1\right] be some probability measure. Here we give an argument to encode μ\mu into a kernel function M:[0,1]2ΩM:\left[0,1\right]^{2}\rightarrow\Omega, and use this notion to reinterpret the assumptions of the Replica Symmetry Breaking ansatz (RSB) of Parisi et Al. [1, 2], without using replicas, nor averaging on the disorder.
