一类非共轭边值问题 Green 函数定号的最优区间
T he optimal interval for Green's function having a constant sign of a non-conjugate boundary value problem
摘要
Abstract
The existence of the optimal interval is proved , such that the Green's function of a disconjugate differential equation with non‐conjugate boundary condition will get negative sign when the parameter is in this interval . Then , the left and right endpoints of this interval are found by backward searching method .关键词
