      In the present note we study an approximate method of solving boundary value problems for delay integro-differential equations based on approximation of the solution by cubic splines with defect two.
    • On the approximation of linear systems with delay and their stability 

      Piddubna, Larisa; Tuzyk, Iryna; Cherevko, Ihor (The 28th Conference on Applied and Industrial Mathematics 17th(18th September),- Book of Abstract., 2021-09-17)
      In the present paper, we consider applications of the approximation schemes for differential-difference equations to approximate finding nonasymptotic roots of quasipolynomials and analysis of stability for solutions of ...
