چکیده
By using a fixed point theorem of strict-set-contraction, some sufficient conditions are obtained for the existence of positive periodic solutions for a periodic neutral Lotka-Volterra competition system on time scales of the form x ∆ i (t) = x i (t) r i (t) − n j=1 a ij (t)x j (t) − n j=1 b ij (t)x j (t − τ ij (t, x 1 (t),. .. , x n (t))) − n j=1 c ij (t)x

متن کاملTHE QUALITATIVE ANALYSIS OF iv-SPECIES LOTKA-VOLTERRA PERIODIC COMPETITION SYSTEMS
In this paper, we consider an n-species Lotka-Volterra periodic competition system. Using a comparison method and the Brouwer fixed point theorem, we obtain some sufficient conditions for the ultimate boundedness of solutions and the existence and global attractivity of a positive periodic solution. We also point out that these results constitute a generalization of K. Gopalsamy and J. M. Cushi...
