Comparison theorems for Lorentzian length spaces with lower timelike curvature bounds
Waldemar Barrera, Luis Montes de Oca, Didier A. Solis
In this article we introduce a notion of normalized angle for Lorentzian pre-length spaces. This concept allows us to prove some equivalences to the definition of timelike curvatur…

Smooth Knot Limit Sets of the Complex Hyperbolic Plane
Waldemar Barrera, Rene Garcia, Juan Pablo Navarrete
It is shown that if a regular knot of class C2 is embedded in the boundary of the complex hyperbolic plane as the limit set of a discrete subgroup of PU(2, 1) then it is either a c…
