Relative Quasiconvexity using Fine Hyperbolic Graphs
Relative Quasiconvexity Fine Hyperbolic Graphs
font style='font-size:12px;'>
2010/12/8
We provide a new and elegant approach to relative quasi-convexity for relatively hyperbolic groups in the context of Bowditch’s approach to relative hyperbolicity using cocompact actions on fine hy-pe...

In this paper we introduce a new geometric ow | the hyperbolic gradient ow for graphs in the (n + 1)-dimensional Euclidean space Rn+1.

Tropicalization is a procedure for associating a polyhedral complex to a subva-riety of an algebraic torus. We study the question on which graphs arise from tropicalizing algebraic curves. By using Ba...
