AbstractWe study scattering rigidity in Lorentzian geometry: recovery of a Lorentzian metric from the scattering relation known on a lateral boundary. We show that, under a non-conjugacy assumption, every defining function r(x,y) of the submanifold of pairs of boundary points which can be connected by a lightlike geodesic plays the role of the boundary distance function in the Riemannian case i...
SpeakerMy research subjects contain complex algebraic-analytic geometry, complex hyperbolicity, non-abelian Hodge theories in both Archimedean and non-Archimedean settings, Nevanlinna theory, and the interplay among them. My current interest is harmonic mapping to Euclidean buildings, linear Shafarevich conjecture, hyperbolicity of algebraic varieties via representation of fundamental groups.Co...
