【摘要】 考察一个解在加权空间中的二阶边值问题,其非线性项关于时间变量可以奇异。通过引入适当的高度函数并且考察此函数的积分,证明一个存在定理,改进了已有的结论。更多还原

【Abstract】 A nonlinear second-order two-point boundary value problem with the solutions in weighted spaces is considered. In this problem,the nonlinear term may be singular with respect to the time variable. By introducing a suitable height function and considering its integral,an existence theorem is proved. This theorem obviously extends an existing result.更多还原
