一类四阶两点边值问题的正解
Positive Solutions of Fourth-order Two-point Boundary Value Problems
【摘要】 运用锥上的不动点定理,研究了非线性四阶常微分方程两点边值问题u(4)(t)=f(t,u(t)),t∈(0,1),u(0)=u′(1)=u″(0)=u(1)=0的正解的存在性.
【Abstract】 The existence of positive solutions to the two-point boundary value problemu4(t)=f(t,u(t)),t∈(0,1),u(0)=u′(1)=u″(0)=u(1)=0is discussed.An existence theorem of at least one positive solutionis is obtained by using the fixed point theorem in a cone.
