    • Accuracy of Euler’s γ expansion without logarithm 

      Mačys, Juozas Juvencijus; Banys, Rimas (Lietuvos matematikos rinkinys : Lietuvos matematikų draugijos darbai. Serija A, 2014)
      The rational approximations for the Euler–Mascheroni constant γ using the Euler asymptotic expansion are obtained. The errors of approximations are evaluated. The numerical computations reflect the accuracy of the approximations.

    • Analysis of splitting schemes for 2D and 3D Schrödinger problems 

      Mirinavičius, Aleksas (Lietuvos matematikos rinkinys : Lietuvos matematikų draugijos darbai. Serija A, 2012)
      New splitting finite difference schemes for 2D and 3D linear Schrödinger problems are investigated. The stability and convergence analysis is done in the discrete L2 norm. It is proved that the 2D scheme is unconditionally ...

    • Bitcoin – a way to reach consensus in a completely decentralized manner 

      Bieliauskas, Rytis; Paliokas, Eugenijus (Lietuvos matematikos rinkinys : Lietuvos matematikų draugijos darbai. Serija A, 2016)
      Bitcoin is a digital currency currently being legalized throughout the European Union [ 2 ], whose operating principles were published publicly [ 5 ], but not in scientific or mathematical sources. The goal of this report ...

    • Discounted payments theorems for large deviations 

      Kasparavičiūtė, Aurelija; Deltuvienė, Dovilė (Lietuvos matematikos rinkinys : Lietuvos matematikų draugijos darbai. Serija A, 2016)
      Let Z (t) =∑ N (t) j =1 Xj, t ≥ 0 , be a stochastic process, where Xj are independent identically distributed random variables, and N (t) is non-negative integer-valued process with independent increments. Throughout, we ...

    • Eliciting opinions of experts using uncertainty 

      Podvezko, Valentinas; Podviezko, Askoldas (Lietuvos matematikos rinkinys : Lietuvos matematikų draugijos darbai. Serija A, 2015)
      Multiple criteria decision-making (MCDM) methods designed for evaluation of attractiveness of available alternatives, whenever used in decision-aid systems, imply active participation of experts. They participate in all ...

    • On large deviations for compound mixed Poisson process 

      Kasparavičiūtė, Aurelija; Deltuvienė, Dovilė (Lietuvos matematikos rinkinys : Lietuvos matematikų draugijos darbai. Serija A, 2013)
      This paper is designated for normal approximation to the distribution function of the compound mixed Poisson process taking into consideration large deviations both in the Cramér and power Linnik zones.

    • On large deviations for random sums of the squares of weighted Gaussian random variables 

      Kasparavičiūtė, Aurelija; Deltuvienė, Dovilė (Lietuvos matematikos rinkinys : Lietuvos matematikų draugijos darbai. Serija A, 2015)
      The paper considers normal approximation to the distribution of random sums of the squares of independent weighted Gaussian random variables (r.vs.) taking into consideration large deviations in the Cramér zone.

    • The construction of test reliability statistical criteria by a computer simulation 

      Navickienė, Olga; Krylovas, Aleksandras; Kosareva, Natalja (Lietuvos matematikos rinkinys : Lietuvos matematikų draugijos darbai. Serija A, 2013)
      The paper describes a computer simulation experiment of knowledge assessment test when item’s characteristic functions are power functions and knowledge level of the population has uniform or normal distribution. The ...
