ABSTRACT
Schur's Theorem on integer colouring states that colouring integers using finitely many colours yields at least one monochromatic solution to the equation . An extension of Schur's theorem on integer lattices is explored by Vishal Balaji, Andrew Lott and Alex Rice. Schur tried to prove Fermat's Last Theorem by proving non-existence of the solution to the equation
for prime
. But he in fact proved that "for every integer
, there exists
such that for any prime
, the congruence
has a solution" where he failed to prove Fermat's Last Theorem in this route of attack. This demonstrates that Fermat's Last Theorem does not hold in the finite field
for any sufficiently large prime
. We investigate Schur's Theorem on integer colouring and the corresponding theoretical framework in algebraic groups, and we classify colourings that yield a monochromatic solution to
(not all are equal). We use combinatorial tools like bijective counting and Pigeonhole principle to arrive at Theorem 3.9. Our methods include Principle of Inclusion-Exclusion formula to prove the principal result Theorem 3.20. We have used Python language to implement algorithms developed during the research to showcase Schur triples associated to the group
and some given colouring maps. We illustrated various groups and its colouring properties. We were able to find bounds using certain parameters involving special subgroups of the group for Schur triples
such that
and
get the same colour in algebraic groups when coloured using finitely many colours. We also find the connection between proper vertex colouring and group colouring via Cayley graphs of semigroups. Our study throws light on new combinatorial perspectives on colouring problems on finite algebraic groups. The results help to enhance new algorithms related to Cayley graph colourings associated with finite semigroups. The research helps in combinatorial studies equipped by colouring problems involving network theory.
