    We extend the concept of the ergodic set [1] – [2] from topological trans-formation groups to topological transformation semigroups. We investigate, in par-ticular, connections between ergodicity, weak ergodicity, topological ...

    We study the behavior of solutions of the problemεu′′(t)+u′(t)+Au(t) =f(t), u(0) =u0, u′(0) =u1in the Hilbert spaceHasε→0, whereAis a linear,symmetric, strong positive operator.
  • Glavan, Vasile; Rzeszotko, Z. (Institutul de Matematică şi Informatică al AŞM, 2003)
    Linear Poisson actions of the groupRmare considered. Conditions on thejoint spectrum of the generators and on the centralizers assuring stability and strongstability of the action are given. We give also some examplesof ...
  • Cheban, David; Kloeden, Peter-E.; Schmalfuss, Bjorn (Institutul de Matematică şi Informatică al AŞM, 2003)
    This article is devoted to the study of the compact global atrractors of Vmomotone nonautonomous dynamical systems.We give a description of the structure of compact global attractors of this class of systems. Several ...
  • Fonoberova, Maria; Lozovanu, Dmitrii (Institutul de Matematică şi Informatică al AŞM, 2004)
    In this paper we study the dynamic version of the nonlinear minimum- cost flow problem on networks. We consider the problem on dynamic networks with nonlinear cost functions on edges that depend on time and flow. Moreover, ...
  • Cheban, David; Mammana, Cristiana (Institutul de Matematică şi Informatică al AŞM, 2004)
    The article is devoted to the study of absolute asymptotic stability ofdiscrete linear inclusions (both autonomous and non-autonomous) in Banach space.We establish the relation between absolute asymptotic stability, uniform ...
  • Spinu, Efimii (Institutul de Matematică şi Informatică al AŞM, 2004)
    In this paper we build a basis in a separable symmetrically normed ideal.
  • Cheban, David; Mammana, Cristiana (Institutul de Matematică şi Informatică al AŞM, 2006)
    The article is devoted to the study of absolute asymptotic stability of discrete linear inclusions in Banach (both finite and infinite dimensional) space. We establish the relation between absolute asymptotic stability, ...
  • Capcelea, Titu (Institutul de Matematică şi Informatică al AŞM, 2006)
    The computation schemes of collocation and mechanical quadraturemethods for approximate solving of the complete singular integral equations withpiecewise continuous coefficients and a regular kernel with weak singularity ...

    We prove that in the class of abstract multidimensional manifolds withoutborders only torusVn1of dimensionn≥1 can be divided in abstract cubes with theproperty: every faceImfromVn1is shared by 2n−mcubes,m= 0,1, . . . , ...
  • Bejan, Andrei (Institutul de Matematică şi Informatică al AŞM, 2006)
    We investigate here how to treat numerically the Kendall functional equa-tion occuring in the theory of branching processes and queueing theory. We discussthis question in the context of priority queueing systems with ...
  • Bujac, Mariana (Institutul de Matematică şi Informatică al AŞM, 2006)
    n the paper [3] we tried to generalize the problem of existence of a di-rected (n−1)-dimensional Euler tour for the abstract directedn-dimensional manifold,which is acomplex of multi-ary relations[5], namely by means of ...
  • Shenesheutskaia, Alla (Institutul de Matematică şi Informatică al AŞM, 2006)
    The connection between junior groups of three independent kinds ofantisymmetry transformations and junior groups of (221)-symmetry, derived fromspace Fedorov groups was established. This connection allowed us to find all ...
  • Cucu, Ion V. (Institutul de Matematică şi Informatică al AŞM, 2006)
    We examine chain logicsC2, C3, . . . ,which are intermediary betweenclassical and intuitionistic logics. They are also the logics of pseudo-Boolean algebrasof type< Em,&,∨,⊃,¬>, whereEmis the chain 0< τ1< τ2<···< τm−2<1 ...

    We study asymptotic average scheme for semi-Markov queuingsystemsusing compensating operator of the corresponding extendedMarkov process. Thepeculiarity of our queuing system is that the series scheme is considered with ...

    The numerical algorithms for solution of multidimensionalanalogs of theKendall (Kendall-Takacs) equation, including effective fast algorithm are discussed.
  • Cataranciuc, Sergiu; Soltan, Petru (Institutul de Matematică şi Informatică al AŞM, 2010)
    The complex of multi-ary relations Kn is defined in a more natural way than it was defined in [18, 58, 59]. The groups of homologies and co-homologies of this complex over the group of integer numbers are constructed. The ...

    In this paper we prove that an asymptotic equilibrium of an affine systemof differential equations can become a strange attractor under affine impulsive control.The linear oscillator is studied as example.
