A characterization of the graphs of bilinear $(d\times d)$-forms over ${\mathbb{F}}_2$

Alexander L. Gavrilyuk, Jack H. Koolen

The bilinear forms graph denoted here by $Bi{l}_q(e\times d)$ is a graph defined on the set of $(e\times d)$-matrices ($e\ge d$) over ${\mathbb{F}}_q$ with two matrices being adjacent…
