  • Radicals and generalizations of derivations 
    COJUHARI, Elena; GARDNER, Barry (Institutul de Matematică şi Informatică al AŞM, 2017)
    By results of Slin’ko and of Anderson, the locally nilpotent and nil radicals of algebras over a field of characteristic 0 are preserved by derivations. This note deals with radical preservation by various generalizations ...
  • About one special inversion matrix of non-symmetric n-IP-loop 
    URSU, Leonid (Institutul de Matematică şi Informatică al AŞM, 2017)
    It is known that n-IP-quasigroups have more than one inversion matrix. It is proved that one of these inversion matrices in the class of non-symmetric n-IP-loops is so-called matrix [Iij ] of permutations, any of which has ...
  • Max-Erlang and Min-Erlang power series distributions as two new families of lifetime distribution 
    LEAHU, Alexei; MUNTEANU, Bogdan Gheorghe; CATARANCIUC, Sergiu (Institutul de Matematică şi Informatică al AŞM, 2014)
    The distribution of the minimum and maximum of a random number of independent, identically Erlang distributed random variables are studied. Some particular cases of such kind of lifetime distributions are discussed too.
  • On generalization of the notion of Moufang loop to n-ary case 
    ONOI, Vasile; URSU, Leonid (Institutul de Matematică şi Informatică al AŞM, 2019)
    Using isotopical approach we generalize concept of binary Moufang loop on n-ary (n > 2) case. We give two examples of ternary Moufang loop which are not a ternary group.
  • On existential expressibility of formulas in the simplest non-trivial super-intuitionistic propositional logic 
    RUSU, Andrei; RUSU, Elena (Institutul de Matematică şi Informatică al AŞM, 2017)
    We consider the well-known 3-valued extension of the intuitionistic propositional logic [1] and examine the conditions for o system of formulas to be complete with respect to existential expressibility of formulas considered ...
  • On the inverse operations in the class of preradicals of a module category 
    JARDAN, Ion (Institutul de Matematică şi Informatică al AŞM, 2017)
    In the class PR of preradicals of the category of left R-modules RMod a new operation is defined and studied, namely the left quotient with respect to join. Some properties of this operation are shown, its compatibility ...
  • On the left coquotient with respect to meet for pretorsions in modules 
    JARDAN, Ion (Institutul de Matematică şi Informatică al AŞM, 2017)
    In the operation of left coquotient with respect to meet for preradicals of R-Mod is defined. In the present short notice the particular case of pretorsions of R-Mod is considered. We prove that for pretorsions the studied ...
  • First integrals with polynomials not higher than second order of the mathematical model of the intrinsic transmission dynamics of tuberculosis 
    NEAGU, Natalia; POPA, Mihail; ORLOV, Victor (Institutul de Matematică şi Informatică al AŞM, 2014)
    For the mathematical model of the intrinsic transmission dynamics of tuberculosis (TB) all first integrals with polynomials not higher than second order were found.
  • About one special inversion matrix of 3-ary and 4-ary IP-loops 
    URSU, Leonid (Institutul de Matematică şi Informatică al AŞM, 2014)
    It is known that an n-IP-quasigroup can have more than one inversion matrix. We prove that one of these matrices for a 3-ary IP-loop and for a 4-ary IP-loop is the matrix of permutations every of which fixes identity of a ...
  • Relative torsion theories 
    BOTNARU, Dumitru; ŢURCANU, Alina (Institutul de Matematică şi Informatică al AŞM, 2014)
    We formulate necessary and sufficient conditions for a pair of subcategories to form a relative torsion theory.
  • An approach for NL text interpretation 
    POPESCU, Anatol; CREŢU, Sergiu (Institutul de Matematică şi Informatică al AŞM, 2007)
    For modeling the interpretation process of NL sentences we use the mechanisms implying semantic networks that assure syntactic – semantic text interpretation (SSI), including an understanding axiomatic model, interpretation ...
  • The application of Mathematica to research the restricted eight bodies problem 
    CEBOTARU, Elena (Institutul de Matematică şi Informatică al AŞM, 2018)
    Newton’s restricted problem of eight bodies is investigated. In this paper an effective way of determining the stationary points of differential equations describing this problem is exposed. Analytic and numerical calculations ...
  • Membrane Systems Languages Are Polynomial-Time Parsable 
    ALHAZOV, Artiom; CIUBOTARU, Constantin; IVANOV, Sergiu; ROGOZHIN, Yurii (Institutul de Matematică şi Informatică al AŞM, 2010)
    The focus of this paper is the family of languages generated by transitional non-cooperative P systems without further ingredients. This family can also be defined by so-called time yields of derivation trees of context-free ...
  • Text Classification Using Word-Based PPM Models 
    BOBICEV, Victoria (Institutul de Matematică şi Informatică al AŞM, 2006)
    Text classification is one of the most actual among the natural language processing problems. In this paper the application of word-based PPM (Prediction by Partial Matching) model for automatic content-based text ...

  • Apportionment “Population paradox” and the Paradox of population influence 
    BOLUN, Ion (Institutul de Matematică şi Informatică al AŞM, 2020)
    A new approach is grounded with respect to the population paradox (PPr). Further on, the paradox of population influence (PPi) is proposed. It is proven that Hamilton method is immune to the PPi, and that d’Hondt, ...
