Is it possible to give a more precise formulation of the criterion of maximal accretivity for one extension of nonnegative operator?

The conditions being necessary and sufficient for maximal accretivity and maximal nonnegativity of some closed linear operators in Hilbert space are announced. The following problem is proposed: write down these conditions in more convenient form (one of the admissible variants is indicated).
