  • Mathematical Model in Studying the Stability of Dynamic Systems

    • Authors: Le, Hong Lan (2017)

  • In this paper, the author investigated the phenomenon of flutter, which may be the cause of instability of construction structure when it is affected by aerodynamics. By analyzing the effect of aerodynamic on the structure via mathematical analysis, the author has established a mathematical model to study the stability of the structure in the aerodynamic flux that moves supersonically.

  • On The Convergence of Stability Domain on Time Scales

    • Authors: Nguyen, Thu Ha; Khong, Chi Nguyen; Le, Hong Lan (2015)

  • This paper studies convergence of the stability domains for a sequence of time scales. It is proved that if the sequence of time scales (Tn) converges to a time scale T in Hausdorff topology then their stability domains UTn will converge to the stability domain UT of T.

  • Predator-prey System with the Effect of Environmental Fluctuation

    • Authors: Le, Hong Lan (2014)

  • In this paper we study the trajectory behavior of Lotka - Volterra predator - prey systems with periodic coefficients under telegraph noises. We describe the - limit set of the solution, give sufficient conditions for the persistence and prove the existence of a Markov periodic solution.

  • Stability Radii for Difference Equations with Time-varying Coefficients

    • Authors: Le, Hong Lan (2010)

  • This paper deals with a formula of stability radii for an linear difference equation(LDEs for short) with the coeffecients varying in time under structured parameter perturbations. It is shown that the Ip- real and complex stability radii of these systems coincide and they are given by a formula of input-output operator. The result is considered as an discrete version of a previous result for time-varying ordinary differential equations.
