Combinatorics and physics ice-type model is six vertex model with domain wall boundary conditions. Combinatorics and physics Combinatorial physics or physical combinatorics is the area of interaction between physics and combinatorics. "Combinatorial Physics is an emerging area which unites combinatorial and discrete mathematical techniques applied to theoretical physics, especially Quantum Theory.". "Physical combinatorics might be defined naively as combinatorics guided by ideas or insights from physics". Combinatorics has always played an important role in quantum field theory and statistical physics. However, combinatorial physics only emerged as a specific field after a seminal work by Alain Connes and Dirk Kreimer, showing that the renormalization
Interaction information Interaction information The interaction information (McGill 1954), or amounts of information (Hu Kuo Ting, 1962) or co-information (Bell 2003) or information interaction (Licina 2017) is one of several generalizations of the mutual information. In fact, the definition of interaction information is identical to that of multivariate mutual information except for a change in sign in the case of an odd number of random variables except in the work of Licina where information is more like a physical entitiy. Interaction information expresses the amount information (redundancy or synergy) bound up in a set of variables, "beyond" that which is present in
