What you want to ask is who first proposed the young Baxter equation? Yang Zhenning. After Yang Zhenning joined the State University of New York at Stony Brook on 1966, he quickly put forward the Young Baxter equation, which reflects the topological translation invariance of directed paths, which is the fundamental reason why the equation plays an important role in many fields of physics and mathematics. In the fields of completely integrable statistical model, * * shape field theory, topological field theory, braid group theory, circle conclusion, Newtonian conclusion and so on, Young Baxter equation is all.
