Galois or finite fields are important in number theory, algebraic geometry, Galois Theory, cryptography, coding theory and error correction. Finite fields have applications in many areas of mathematics and computer science, including coding theory, linear feedback shift registers (LFSRs).  The talk will first introduce the definition of fields with examples. It then describes the Fermat’s little theorem, multiplicative inverse, primitive roots. Then describe the special case of GF(2n) and Rijndael’s finite field GF(28). We will finish with applications of Galois Fields to error control codes such as CRC and BCH.
