Stieltjes and inverse Stieltjes holomorphic families of linear relations and their representations
Yury Arlinski\uı, Seppo Hassi
We study analytic and geometric properties of Stieltjes and inverse Stieltjes families defined on a separable Hilbert space and establish various minimal representations for them b…

Lebesgue type decompositions for linear relations and Ando's uniqueness criterion
Seppo Hassi, Zoltán Sebestyén, Henk de Snoo
A linear relation, i.e., a multivalued operator from a Hilbert space to a Hilbert space has Lebesgue type decompositions , where…
