On oscillation and asymptotic behaviour of a neutral differential equation of first order with positive and negative coefficients Radhanath Rath, Prayag Prasad Mishra, Laxmi Narayan Padhy Abstract: In this paper sufficient conditions are obtained so that every solution of tends to zero or to as tends to , where are positive real numbers, , and , is non decreasing with for . The two primary assumptions in this paper are and . The results hold when is linear, super linear,or sublinear and also hold when . This paper generalizes and improves some of the recent results in [5,7,8,10]. Submitted November 2, 2006. Published January 2, 2007 Math Subject Classifications: 34C10, 34C15, 34K40. Key Words: Oscillatory solution; nonoscillatory solution; asymptotic behaviour. Show me the DVI (62K), PDF (216K), TEX and other files for this article. source from : ELECTRONIC...
