MaPSS: Maths Postgraduate Seminar Series: Joel Gibson -- An introduction to error-correcting codes

Hello all,

The next MaPSS talk of this semester will be at 17:00 on Mon 15th April in Carslaw 535.
It’s a great opportunity to meet fellow postgrads, listen to an interesting talk, and of
course get some free pizza!

Speaker: Joel Gibson

Title: An introduction to error-correcting codes

Abstract: Error-correcting codes are used all over the digital world to detect and
recover from various errors, whether they be a noisy connection, a hard-drive failure, a
scratched-up CD, or even a partially-revealed QR code.  Almost all of these algorithms
are algebraic at heart, relying on the properties of linear algebra and polynomials over
finite fields to operate.  In this talk, I cover some of the basics of error detection
and correction, before showing how an optimal encoding algorithm can be built out of
basic algebraic structures, such as vector spaces over Z/pZ, the integers modulo a prime
number.
