A virtual $PGL_{r}$ - $SL_{r}$ correspondence for projective surfaces

D. van Bree, A. Gholampour, Y. Jiang +1

For a smooth projective surface $X$ satisfying $H_{1} (X, Z) = 0$ and $w \in H^{2} (X, μ_{r})$ , we study deformation invariants of the pair $(X, w)$ . Choosing a Brauer-Severi variety…

From $χ$ - to $χ_{p}$ -bounded classes

Y. Jiang, J. Nesetril, P. Ossona de Mendez

$χ$ -bounded classes are studied here in the context of star colorings and more generally $χ_{p}$ -colorings. This leads to natural extensions of the notion of bounded expansion class…
