| contents | This study examines the fractional chromatic number associated with the direct product of signed graphs. It shows that if $(H,τ)$ is a signed circulant graph $G(n,S,T)$, then for any signed graph $(G,σ)$, the fractional chromatic number of their direct product is the lower number between the fractional chromatic number of $(G,σ)$ and $(H,τ)$. |
