Abstract: It starts with an empirical observation that a certain polynomial in a certain family of commuting operators with lots of positive and negative coefficients turns out to have all positive matrix elements. Why should it be so? This story features stochastic six-vertex models, symmetric functions, Robinson-Schensted-Knuth correspondence, and Yang-Baxter equation.
