Boundary values of resolvents of self-adjoint operators in Krein spaces
Vladimir Georgescu, Christian Gérard, Dietrich Häfner
We prove in this paper resolvent estimates for the boundary values of resolvents of selfadjoint operators on a Krein space: if is a selfadjoint operator on a Krein space $\cH$,…

Binding condition for a general class of quantum field Hamiltonians
Christian Gérard, Itaru Sasaki
We consider a system of a quantum particle interacting with a quantum field and an external potential $V(\bx)$. The Hamiltonian is defined by a quadratic form $H^V = H^0 + V(\bx)$,…
