Balancing related methods for minimal realization of periodic systems [PDF]
, 1999 We propose balancing related numerically reliable methods to compute minimal realizations of linear periodic systems with time-varying dimensions. The first method belongs to the family of square-root methods with guaranteed enhanced computational ...

Global positive periodic solutions of periodic n-species competition systems
Journal of Mathematical Analysis and Applications, 2009 Lotka-Volterra systems have been investigated extensively for the last decades. Many results dealing with the global existence and attractivity of periodic solutions have been obtained. As an extension of the Lotka-Volterra models in 1973, a more complicated model was proposed by Gilpin and Ayala.

POSITIVE PERIODIC SOLUTIONS OF SYSTEMS OF FUNCTIONAL DIFFERENTIAL EQUATIONS [PDF]
Journal of the Korean Mathematical Society, 2005 The authors study the existence of the positive periodic solutions of the functional differential equations \[ x'(t)=A(t)x(t)+\lambda f(t, x(t-\tau(t))). \] By applying a cone theoretic fixed point theorem, the authors obtain some sufficient conditions for the existence of positive periodic solutions of the above equation.
