一类非齐次边界值问题广义解的存在性

目的讨论了一类非线性偏微分方程组非齐次边界条件下广义解存在性问题．此方程组是在聚合物加工中提出来的，它描述了缝模中不可压缩非牛顿粘性流体非定常流动的规律．方法应用了单调算子理论和Schauder不动点定理．结果与讨论在合理的条件下，证明了方程组在非齐次边界条件下广义解的存在性．

The Existence of Generalized Solutions for a Nonhomogeneous Boundary Value Problem

Aim The existence of generalized solution for a class of nonlinear partial differential equations with nonhanogeneous boundary condition was investigated. This problem arises from polymer processing concerned with the first initial-boundary value problem or the nonstationary floW of non-Newtonian viscous incompressiblee fluid through the slit dice. MethodsThe monotone operator theory and the Schauder's fixal point theorem were used. Results and Conclusion The existence theorem of generalized solutions for a the of nonlinear partial differential equations with nonhormogeneous boundary condition is proved under reasonable conditions
