prerequisites for understanding game theory I am from programming background but with very limited knowledge of maths.
I am very much eager to learn and apply game theory to understand dynamics of International Politics and economics. But I am facing difficulties to understand the maths involved in it. 
So, 


*

*What are prerequisites for understanding the math in the game theory?

*What are the authentic sources to understand game theory mathematically and 
and its application in the international politics and economics? 

 A: As @JordanMahar mentions, Fudenberg and Tirole is the standard graduate-level text. But I would start with Game Theory for Applied Economists by Gibbons. It is very readable. 
Prerequisites for Gibbons are minimal. A little algebra and probability will do just fine. 
A: In economics, the classic source for game theory is:
Fudenberg, D. and Tirole, J. (1991). Game Theory
At least with Game Theory applied to economics, you can begin with a minimal knowledge of mathematics (applied calculus and some set theory will usually suffice). 
A: *

*Secondary-school math. And since game theory is essentially math, along the way you'll learn more math.

*Ken Binmore's Playing for Real: A Text on Game Theory is suitable for undergraduates and doesn't get heavily mathematical at all.

*What is game theory about?
  
*How do I apply game theory?
  
*Why is game theory right?
  

There's even a marker in the margin in places where you're allowed to skip some of the math and move on to the next bit.

It isn't easy to write in a light-hearted style when presenting mathematical material, but I did my best.

I think he did an excellent job.
