Trace Formulae for Dissipative and Coupled Scattering Systems,For scattering systems consisting of a (family of) maximal dissipative extension(s) and a self-adjoint extension of a symmetric operator with finite deficiency indices, the spectral shift function is expressed in terms of an abstract Titchmarsh-Weyl function and a variant of the Birman-Krein formula is proved.

Gila Perkphically convex domain is equivalent to a .. These domains are shown to be pseudoconvex (Cartan–Thullen). The converse (Levi’s problem) was proved by K. Oka and the complete proof is presented here. We will see again that Oka’s Jôku-Ikô plays an essential role.
