具非负特征形式的二阶微分方程的第一边值问题

FIRST BOUNDARY VALUE PROBLEM OF SECOND ORDER DIFFERENTIAL EQUATIONS WITH NONNEGATIVE CHARACTERI FORM

本文研究具有非负特征形式的二阶微分方程的一个新的第一边值问题,在有界可测函数空间中弱解的存在性,并用共扼算于方法讨论解为唯一的条件.

This paper consideres the modified first boundary value problem of second order differential equations with nonnegative characteristic form. And discusses the existence of weah solution of the space of bounded measurable functions and the conditions of uniqueness of solution.
