  • Entropy and F-divergence construction using the Einstein sum 
    PATRASCU, Vasile (Bons Offices, 2018)
    Starting from the Einstein sum and considering the real parameter a ∈ (1, ∞), we define the function f : [0, ∞) → (−∞, ∞) with the formula. Using the function f, the following formulas for entropy Hf and f-divergence Df ...
  • Estimates for Solutions to Partial Quasilinear Differentila Equations 
    BALTAG, Iurie (Bons Offices, 2018)
    Let’s consider L(u) = a(x, t)utt + b(x, t)utx + c(x, t)uxx + d(x, t)ut + h(x, t)ux, x ∈ R1. The second order quasilinear equations are studied in the following form: L(u) + r(u) a(x, t)u 2 t + b(x, t)utux + c(x, t)u 2 x + ...
  • Inverse problem for a two-dimensional strongly degenerate heat equation 
    IVANCHOV, Mykola; VLASOV, Vitaliy (Bons Offices, 2018)
    We consider an inverse problem for a two-dimensional degenerate heat equation in a rectangular domain. Direct problems of this type are mathematical models of various processes such as seawater desalination, movement of ...
  • Methods of solving perfect informational games 
    HÂNCU, Boris (Bons Offices, 2018)
    For any strategies profile (θ1, θ2) it is constructed the normal forms of game on set of informationally nonextended strategies X, Y.
  • On generalization of expressibility in 5-valued logic 
    CUCU, Ion (Bons Offices, 2018)
    Let us consider the pseudo-Boolean algebra (M; ∧, ∨, ⊃, ¬), where ⊃ is relative pseudo-complement, and ¬ is pseudo-complement. We say that the system of pseudo-Boolean terms on the set of variables X (Ω – words over X ) ...
  • On the generalized factorization of functions in weighted spaces 
    MOLOȘNIC, Petru; NEAGU, Vasile (Bons Offices, 2018)
    In this paper the notion of factorization of functions with respect to contour Γ in the spaces Lp(Γ, ρ) is presented. The main result of the paper is the determination of some classes of functions that allow a factorization, ...
