By using a fixed point theorem of mixed monotone operators in cone, this paper studied a fourth-order nonlinear singular boundary value problem, namely a class of elastic beam equation.
利用锥上的混合单调算子不动点定理,本文研究了一类四阶奇异非线性微分方程的边值问题,即一类弹性梁方程问题。
Therefore, the present problem is indeed a problem of nonlinear boundary value. The mixed boundary conditions involve unknown intervals (the slip, separation and stick zones). It …
由于边界上的区域(滑移、分离和粘着)是未知的,所以,笔者研究的实际上是个复杂的边界非线性问题。
