We prove using the Faedo‐Galerkin method the existence of a generalized solution of an initial‐boundary value problem for the non‐linear evolution equation0 ⩽ Q ⩽ 2, in a cylinder Q T = Ω × (0, T), where u = yu xx + u yy is the Tricomi operator and l(u) a special differential operator of first order. We then show that the approximate generalized solution of problem (*) converges to the approximate generalized solution of the corresponding stationary boundary value problem as t → ∞.
