Polygonal surfaces in pseudo-hyperbolic spaces

Apparaît dans la collection : 2025 - T2 - WS1 - Higher rank geometric structures, Higgs bundles and physics

A polygonal surface in the pseudo-hyperbolic space is a complete maximal surface bounded by a lightlike polygon with finitely many vertices. Among maximal surfaces, polygonal surfaces admit several characterizations : being asymptotically flat or having finite total curvature. In this talk we will explain some constructions coming from nonpositive curvature geometry to prove the equivalence, for a maximal surface, between being polygonal and having finite total curvature.
