en عمومى General پژوهشي Research paper <div style="text-align: justify;">In this paper, the oscillatory behavior of the solutions for a n-dimensional system of coupled van der Pol oscillators with delays is investigated. We extend the result in the literature from mathematical point of view. some sufficient condition to guarantee the oscillation of the solutions are provided and computer simulations are given to support the present criteria.</div> Coupled van der Pol oscillator, Delay, Instability, Oscillation. 1 15 http://ijmsi.ir/browse.php?a_code=A-10-7375-1&slc_lang=en&sid=1 Chunhua Feng cfeng@alasu.edu 100319475328460012370 100319475328460012370 Yes Department of Mathematics and Computer Science, Alabama State University, Montgomery, USA, 36104
