Abstract: Configurations of curves on algebraic surfaces provide lots of generalized dessins d'enfants. In the talk we consider the most classical example – 27 lines on cubic surfaces. Considering these surfaces as the real ones we arrive at the genuine dessins, though on non-oriented real surfaces. We discuss several special cases; in particular, the Clebsch diagonal cubic is related to the Bring curve. Language: English
