    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, ...

    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 ...

    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 ...

    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 ...

    In the paper [1] it is proved that abstract cubicn-dimensional torus[2] possesses a directed Euler tour of the same dimension. The result prompts toa new (virtual) device for transmission and reception of information. In ...

    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 ...
  • Guțu, Valeriu (Institutul de Matematică şi Informatică al AŞM, 2008)
    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.

    Aπ-quasigroup is a quasigroup satisfying one of the seven minimalidentities from the V.Belousov’s classification given in [1]. Some general results aboutπ-quasigroups isotopic to groups are obtained by V. Belousovand A. ...
