摘要：

For a wide class of the quadratic forms which are densely defined, symmetric, and singular (uncloseable) in Hilbert space we present a construction of regular (closeable) restrictions which are also densely defined and symmetric. We also give some applications to the singular perturbation theory of self-adjoint operators. (C) 1997 Academic Press
