o In the coordinate pair (10,0.7), x=10 and y=0.7 o 0.7 = a(10)² + b(10) o 0.7 = 100a + 10b. After plotting the coordinate pairs in the quadratic equation we end up with two equations: 1.2 = 9a + 3b and 0.7 = 100a + 10b. We are faced with the obstacle of having two variables, which leads us to simultaneous equations.

Abstract. We introduce a new concept of solution to the KPZ equation which is shown to extend the classical Cole-Hopf solution. This notion provides a factorisation of the Cole-Hopf solution map into a “universal” measurable map from the probability space into an explicitly described auxiliary metric space, composed with a new solution map that has very good continuity properties.
