Cohomology of Hopf C*‐Algebras and Hopf Von Neumann Algebras [PDF]
, 2001 We define two canonical cohomology theories for Hopf C*‐algebras and for Hopf von Neumann algebras (with coefficients in their comodules). We then study the situations when these cohomologies vanish.

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.

OPERATOR VERSIONS OF SHANNON TYPE INEQUALITY
, 2016 In this paper, we present some refinements and precise estimations of parametric ex- tensions of Shannon inequality and its reverse one given by Furuta in Hilbert space operators.

Analysis of the energy decay of a viscoelasticity type equation
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016 In this paper, we study the evolution of the energy density of a sequence of solutions of a problem related to a viscoelasticity model where the viscosity term is a pseudo-differential operator of order 2α with α ∈ (0, 1).

Exactness of Free and Amenable Groups by the Construction of Ozawa Kernels [PDF]
, 2004 Using properties of their Cayley graphs, specific examples of Ozawa kernels are constructed for both free and amenable groups, thus showing that these groups satisfy Property O.

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.

The similarity degree of approximately divisible C*-algebras
, 2013 Let A be a unital approximately divisible C*-algebra. We show that the similarity degree of A is at most 5. Mathematics subject classification (2010): Primary 46L05.

Generalized solenoids and C*-algebras
, 1999 We present the continuous graph approach for some generalizations of the CuntzKrieger algebras. These algebras are simple, nuclear, and purely infinite, with rich Ktheory. They are tied with the dynamics of a shift on an infinite path space.

Orthogonally additive holomorphic functions on C^*-algebras
, 2012 Let A be a C ∗ -algebra. We prove that a holomorphic function of bounded type f : A → C is orthogonally additive on Asa if, and only if, it is additive on elements having zeroproduct if, and only if, there exist a positive functional φ in A∗ , a sequence
