چکیده
For real factors the notions of the coupling constant and the index are introduced and investigated. The possible values of the index for type II1 real factors are calculated, in a similar way as for the complex case. 1 Institut für Angewandte Mathematik, Universität Bonn, Wegelerstr. 6, D-53115 Bonn (Germany); SFB 611; HCM; BiBoS; IZKS; CERFIM (Locarno); Acc.

Wave Propagation Approach to Fluid Filled Submerged Visco-Elastic Finite Cylindrical Shells
Multi-layer orthotropic finite cylindrical shells with a viscoelastic core in contact with fluids are gaining increasing importance in engineering. Vibrational control of these structures is essential at higher modes. In this study, an extended version of the wave propagation approach using first-order shear deformation theory of shell motion is employed to examine the free vibration of damped ...

Introduction Selection the appropriate statistical model for the response variable is one of the most important problem in the finite mixture of generalized linear models. One of the distributions which it has a problem in a finite mixture of semi-parametric generalized statistical models, is the Poisson distribution. In this paper, to overcome over dispersion and computational burden, finite ...
متن کاملCohomology for Finite Index Inclusions of Factors
If N ⊆M is an inclusion of type II1 factors of finite index on a separable Hilbert space, and if N has a Cartan subalgebra then we show that H(N ,M) = 0 for n ≥ 1. We also show that H cb(N ,M) = 0, n ≥ 1, for an arbitrary finite index inclusion N ⊆M of von Neumann algebras.
