研究了一类和广义微分算式(在弱导数的意义下)相联系的最小算子和最大算子。
It is shown that the minimal operators are symmetric and the adjoint operators of the minimal operators are exactly the corresponding maximal operators.
最后,在恰当的假设条件下,获得了弱扰动映射的二阶邻接导数的上半连续和下半连续性。
Finally, under suitable assumptions, we obtain the upper semicontinuity and the lower semicontinuity of second-order adjacent derivatives for the weak perturbation maps.
