Cartan Angular Invariant and Deformations in Rank One Symmetric Spaces
Boris Apanasov, Inkang Kim
We develop and study quaternionic and octonionic analogies of Cartan angular and Toledo invariants that are well known in the complex hyperbolic space. Using such invariants we stu…

Two-Dimensional Knots and Representations of Hyperbolic Groups
Boris Apanasov
We describe relations between hyperbolic geometry and codimension two knots or, more exactly, between varieties of conjugacy classes of discrete faithful representations of the fun…
