摘要: 研究了外区域上非牛顿流体方程的Y oung测度解和唯一正则弱解的存在性,并给出一个新的近似结构,其在广义意义下成立。在解性质的讨论和近似解的计算方面,本文的近似结构优于以往的近似结构。Abstract: This paper considers existence of Young measure-valued solutions and a unique regular weak solution for the non-Newtonian flow equations in an exterior domain and gives a new approximation scheme which holds in the sense of distribution.In discussing properties of solutions and calculating of(approximate) solutions,the approximation scheme is better than traditional ones.
