3. Diophantine Equations #
Created Wednesday 29 July 2020
Diohphantine Equations - These are polynomial equations for which integral solutions exist.
We need to study only about linear Diophantine equations.
- Solutions(integral) exist for this if gcd(a,b) is a factor of C.
- We are not going to prove this, but the intuition is easy:
- gcd(a,b) is a factor of a, b
- gcd(a, b) will divide ax+by
- We represent this by c.
e.g has solutions, while has no integral solutions.
- We are studying this in order to apply extended Euclidean algorithm.
