On cubic-line arrangements with simple singularities

Algebraic Geometry 2024-03-27 v2 Combinatorics

Abstract

In the present note we study combinatorial and algebraic properties of cubic-line arrangements in the complex projective plane admitting nodes, ordinary triple and A5A_{5} singular points. We deliver a Hirzebruch-type inequality for such arrangement and we study the freeness of such arrangements providing an almost complete classification.
