Classification of equiangular lines with fixed angle $arccos (1/ (1 + 22))$

Theodore Gossett, Zilin Jiang, Adam Teets +1

We determine the maximum number $N_{α} (d)$ of equiangular lines with fixed angle $arccos α$ for $α = 1/ (1 + 22)$ in $d$ -dimensional Euclidean space: $2,3,4,6,8,10,14,15,16,17,18,20…

Median eigenvalues of subcubic graphs

Hricha Acharya, Benjamin Jeter, Zilin Jiang

We show that the median eigenvalues of every connected graph of maximum degree at most three, except for the Heawood graph, are at most $1$ in absolute value, resolving open proble…
