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.证明了最小算子是对称的,并且最小算子的共轭算子是相应的最大算子.
It is studied that the corresponding minimal and maximal operators associated with a class of generalized differential (in distribution sense) expressions. It is shown that the minimal operators are symmetric and the adjoint operators of the minimal operators are exactly the corresponding maximal operators.
