给出了具有周期边界条件的2n阶微分算子最小特征值的一个下界估计,还给出了具有反周期边界条件的2n阶微分算子最小特征值的一个上界估计.
A lower boundary of the least eigenvalue of 2n- th order differential operators with periodic boundary conditions is obtained, and an upper boundary of the least eigenvalue of 2n- th order differential operators with anti-periodic boundary conditions presented respectively in this paper.
