The Eckardt point configuration of cubic surfaces revisited
Betten, Anton; Karaoğlu, Fatma (Springer, 2022)The classification problem for cubic surfaces with 27 lines is concerned with describing a complete set of the projective equivalence classes of such surfaces. Despite a long history of work, the problem is still open. One ... -
The number of cubic surfaces with 27 lines over a finite field
Karaoğlu, Fatma; Betten, Anton (Springer, 2021)We determine the number of cubic surfaces with 27 lines over a finite field F-q. This is based on exploiting the relationship between non-conical six-arcs in a projective plane embedded in projective three-space and cubic ...
