Abstract
We introduce the concept of z-convergence of linear (not necessarily bounded) operators in a Hilbert space that generalizes the strong resolvent convergence of self-adjoint operators and has the following property: if a sequence of self-adjoint operators z-converges to a linear operator , then is self-adjoint.
