Journal of Mathematical Sciences Aims and scope Submit manuscript

In terms of spaces of boundary values, we formulate and prove criteria of maximal θ-accretivity and maximal nonnegativity for the proper extension of a closed nonnegative linear relation in a Hilbert space. In the case of differential operators, this directly leads to boundary conditions.
