Classification of injective factors: The wok of Alain Connes
International Journal of Mathematics and Mathematical Sciences, Volume 6, Issue 1, Page 1-39, 1983., 1983 The fundamental results of A. Connes which determine a complete set of isomorphism classes for most injective factors are discussed in detail. After some introductory remarks which lay the foundation for the subsequent discussion, an historical survey of some of the principal lines of the investigation in the classification of factors is presented ...

The dual of the multiplier algebra of Pedersen′s ideal
International Journal of Mathematics and Mathematical Sciences, Volume 5, Issue 2, Page 407-409, 1982., 1982 It is shown that the dual of the multiplier algebra of Pederson′s ideal is not always spanned by its positive elements.

On the range of completely bounded maps
International Journal of Mathematics and Mathematical Sciences, Volume 1, Issue 2, Page 209-215, 1978., 1978 It is shown that if every bounded linear map from a C*‐algebra α to a von Neumann algebra β is completely bounded, then either α is finite‐dimensional or β⫅𝒞 ⊗ Mn, where 𝒞 is a commutative von Neumann algebra and Mn is the algebra of n × n complex matrices.

Nuclearity and ${\mathrm {CPC}^*}$ -Systems
Forum of Mathematics, SigmaWe write arbitrary separable nuclear $\mathrm {C}^*$ -algebras as limits of inductive systems of finite-dimensional $\mathrm {C}^*$ -algebras with completely positive connecting maps. The characteristic feature of such ${\mathrm {CPC}^*}$

A posteriori analysis of the spectral element discretization of heat equation
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014 In this paper, we present a posteriori analysis of the discretization of the heat equation by spectral element method. We apply Euler’s implicit scheme in time and spectral method in space.

Approximation of additive functional equations in NA Lie C*-algebras
Demonstratio Mathematica, 2018 In this paper, by using fixed point method, we approximate a stable map of higher *-derivation in NA C*-algebras and of Lie higher *-derivations in NA Lie C*-algebras associated with the following additive functional ...

A simulation algorithm for a single server retrial queuing system with batch arrivals
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015 Many systems of real word are modeled by retrial queuing system with batch arrivals. Analytical formulas for this class of systems are complicated and address only particular cases.

Amenability and Co-Amenability of Algebraic Quantum Groups II.
, 2001 We continue our study of the concepts of amenability and co-amenability for algebraic quantum groups in the sense of A. Van Daele and our investigation of their relationship with nuclearity and injectivity.

A new obstruction to Arveson's hyperrigidity conjecture
Forum of Mathematics, SigmaLet A be a unital $\mathrm {C}^*$ -algebra containing a closed two-sided ideal J and an operator system X. We enlarge X to an operator system $\mathcal{S} (X,J)$ in ${\mathbb {M}}_2(A)$ , and show that in order for $\mathcal{S} (X ...
