Differential Equations Urgent?

Question

Please friends, can you help me to find a good book for delay oscillation Diff. Equations

Answer 1

Try the following:

1. K. Gopalsamy's "Stability and Oscillations in Delay Differential Equations of Population Dynamics"
2. John R. Graef's "Oscillation and Dynamics in Delay Equations"
3. Bainov, D D's Oscillation theory for neutral differential equations with delay

Answer 2

It'd help if you mentioned the order of the system with which you're working

Assuming you mean the most common, 2'nd order, 1'st degree equation(s) there's a pretty good paper (by Agarwal, et. al.) on the subject at

http://web.umr.edu/~bohner/papers/oosodde.pdf

(You'll need Acrobat to read it since it's a .PDF)

You might also check out the 'Electronic Journal of Defferential Equations' at

http://ejde.math.txstate.edu/

to see if there's anything new been published lately.
