Some Results On Line Arrangements
Hakan Güntürkün
Galatasaray Üniversitesi, Turkey
Özet : We will review some classical problems and results about line arrangements in the real and complex projective plane. For real arrangements, Sylvester-Gallai and orchard problems, Dirac-Motzkin conjecture and some comments about the solutions will be given. For complex arrangements we will describe nets as well as some special arrangements. We will present Melchior's and Hirzebruch's inequalities. Finally, after introducing tropical lines, we intend to present some of our own work on the subject.
