讨论四阶常微分方程边值两点问题{u^(4)(t)=f(t,u(t),u"(g)),t∈[0,1],u(0)=u(1)=u"(0)=u"(1)=0的可解性,其中f:[0,1]R R→R连续.该方程是描述两端简单支撑的具有弯曲效应的弹性梁形变的数学模型.在一个新的两参数非共振条件下,获得了解的存在性.
The solvability was discussed of the fourth-order boundary value problem{u^(4)(t)=f(t,u(t),u"(g)),t∈[0,1],u(0)=u(1)=u"(0)=u"(1)=0 which is a model of deformation of an elastic beam with a bending effect, whose two ends are simply supported and where f:[0,1]R R→R is continuous. An existence result was obtained under a new two-parameter nonresonance condition.
