Unitary equivalence of proper extensions of a symmetric operator and the Weyl function
Seppo Hassi, Mark Malamud, Vadim Mogilevskii
Let be a densely defined simple symmetric operator in $\gH$, let $Π=\bt$ be a boundary triplet for and let $M(\cd)$ be the corresponding Weyl function. It is known that t…

On Titchmarsh-Weyl functions of first-order symmetric systems with arbitrary deficiency indices
Sergio Albeverio, Mark Malamud, Vadim Mogilevskii
We study general (not necessarily Hamiltonian) first-order symmetric systems $J y'(t)-B(t)y(t)=\D(t) f(t)$ on an interval with the regular endpoint . The deficiency ind…
