In their results, it is important to solve Tartar’s equation for Young measure and weak entropy pairs, but the part is complicated. In this article, we see an improvement of the part for discrete exponents. In our method, the argument for the part is more simple, and we can relax the restriction of the basic function of the weak entropies.}, pages = {17--34}, title = {1 次元等エントロピー流に対するTartar 方程式の解法の改良}, volume = {27}, year = {2023} }
