Webf : X →Y respecting markings) · Here a diffeomorphism f : X →Y is K-quasiconformal if f′: TX →TY sends infinitesimal circles to ellipses with major and minor axes in ratio 1 ≤M/m ≤ K. Just as conformal maps are hyperbolic isometries, quasiconformal maps distort lengths of closed geodesics by a bounded factor; we have: 1 K WebRecall that a function f : A → B is one-to-one (injective) if ∀x,y ∈ A,f(x) = f(y) → x = y and it is onto (surjective) if ∀y ∈ B,∃x ∈ A,f(x) = y A function that is both one-to-one and onto …
