A complex derivative D®§|¯, with ®; ¯ 2 R+ is a generalization of the concept of integer derivative, where ® = 1; ¯ = 0: By applying the concept of complex derivative, we obtain a high-dimensional parameter space. Amplitude and period values of the periodic solutions of the complex order van der Pol oscillator, are studied for variation of these parameters.engvan der PolOscillatorComplex order derivativeDynamical behaviorconference object
