Uniqueness of solution in a rectangular domain of an evolution dam problem with heterogeneous coefficients. <i>Electronic Journal of Differential Equations, 2018</i>(169), pp. 1-17.1072-6691https://hdl.handle.net/10877/15465In this article, we consider an evolution dam problem with heterogeneous coefficients of type α(x1) (ux2 + χ)x2 - χt = 0 in a bounded rectangular domain of ℝ2. We establish uniqueness of the solution for this problem. Our proofs are based on the test function by using the method of doubling variables.Text17 pages1 file (.pdf)enAttribution 4.0 InternationalEvolution dam problemMethod of doubling variablesUniquenessArticle
