一类半正四阶三点边值问题的解和正解的存在性
Existence of Solutions and Positive Solutions for Semipositone Forth-order Three-point Boundary Value Problems
考察了非线性四阶三点边值问题的解和正解的存在性. 其中允许非线性项有一个负的下界. 主要结论表明该问题可以具有正解, 只要非线性项在某些有界集上的“高度”是适当的。
he existence of solutions and positive solutions is considered for a nonlinear forth-order three-point boundary value problem where nonlinear is allowed to have a negative lower bound .The main results show that the problem may possess positive solutions provided the “height” of nonlinear term are appropriate on some bounded sets.
