# Invited Talk by Dr. Maria Francis on Polynomial Rings over Commutative Rings - Algorithmic techniques and Applications

**Title:**Polynomial Rings over Commutative Rings - Algorithmic techniques and Applications

**Speaker**: Dr. Maria Francis

**Host Faculty:**Dr. N R Aravind

**Room No:**A-220, academic block A.

**Time**:12:00

**Abstract:**

Polynomial rings over commutative rings have applications in several areas like cryptography, control theory, coding theory and algebraic geometry. For example, in lattice based cryptography, most arithmetic operations are over integers, and in control theory parametric equations with polynomials themselves as coefficients are very common.

Algorithmic techniques for polynomial rings over fields are well studied with Groebner bases being one of the fundamental tools. Even though various approaches have been proposed to extend Groebner bases theory to polynomial rings over rings, these techniques have only looked at extending basic definitions and concepts.
