【摘要】 <正> 对退化抛物型方程应如何提边值问题?是否和非退化方程一样可在全抛物正则边界上给初一边值?它与方程系数条件和边界性质有何关系?这些问题近年来已引起人们的注意,并已有不少的研究工作。《二阶拟线性退化抛物型方程的混合边值问题》发表于1980年,其摘要载于美国Math.Reviews,83i,35085。本文将指出文[1]的主要更多还原

【Abstract】 This paper will try to provide an opposite example to the conclusion of the paper [1] in order to illustrate that the main result of [1] is not correct. This paper is also to point out the main causes which result in the errors of [1] is that the author of [1] didn’t consider how the boundary value condition should be suitably given in the degenerate part of the boundary.更多还原
