Title: Oscillatory and asymptotic behavior of solutions for second-order nonlinear integro-dynamic equations on time scales Authors: Ravi P. Agarwal (Texas A&M Univ., Kingsville, TX, USA) Said R. Grace (Cairo Univ., Orman, Giza, Egypt) Donal O'Regan (National Univ. of Ireland, Galway, Ireland) Agacik Zafer (American Univ. of the Middle East, Egaila, Kuwait) Abstract: In this article, we study the asymptotic behavior of non-oscillatory solutions of second-order integro-dynamic equations as well as the oscillatory behavior of forced second order integro-dynamic equations on time scales. The results are new for the continuous and discrete cases. Examples are provided to illustrate the relevance of the results. Submitted September 11, 2013. Published April 15, 2014.
