Eigenvalue-less matrices from SL $_{3} (F_{7})$ to PSL $_{3} (F_{7})$

Juan Lucas Callo, George Chen, Yasiru Jayasooriya +5

We analyse the set of matrices in SL $_{3} (F_{7})$ without eigenvalues explicitly, extracting nice bijections between the 18 equally sized conjugacy classes contained within. I…

Study of Exoo's Lower Bound for Ramsey number $R (5, 5)$

Lachlan Ge, Yasiru Jayasooriya, Alex Qiu +2

We review Exoo's 1989 paper, which demonstrates that a lower bound for the Ramsey number $R (5, 5)$ is $43$ . We provide an efficient way to verify the claims in the paper, adding det…
