Automorphisms of graphs corresponding to conjugacy classes of finite-rank self-adjoint operators

Mark Pankov, Krzysztof Petelczyc, Mariusz Zynel

We consider the graph whose vertex set is a conjugacy class consisting of finite-rank self-adjoint operators on a complex Hilbert space . The dimension of is…

Automorphisms and some geodesic properties of ortho-Grassmann graphs

Mark Pankov, Krzysztof Petelczyc, Mariusz Zynel

Let be a complex Hilbert space. Consider the ortho-Grassmann graph whose vertices are -dimensional subspaces of (projections of rank ) and two subs…
