Combinatorial invariants for nets of conics in $PG (2, q)$

Michel Lavrauw, Tomasz Popiel, John Sheekey

The problem of classifying linear systems of conics in projective planes dates back at least to Jordan, who classified pencils (one-dimensional systems) of conics over $C$ …

Nets of conics of rank one in PG(2,q), q odd

Michel Lavrauw, Tomasz Popiel, John Sheekey

We classify nets of conics in Desarguesian projective planes over finite fields of odd order, namely, two-dimensional linear systems of conics containing a repeated line. Our proof…
