On cubic-line arrangements with simple singularities

  • Przemysław Talar

摘要

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