Abstract:
In ptolemaic spaces the class of η-quasimöbius mappings f: X → Y with control function η(t) = C max[tα, t1/α] may be completely characterized by the inequality K-1 ≤ (1 + log P(fT))/(1 + log P(T)) ≤ K for all tetrads T ⊂ X where P(T) denotes the ptolemaic characteristic of a tetrad. The number K has properties quite similar to those of coefficients of quasiconformality, so the concept of K- quasimöbius mapping may be introduced. In particular, the stability theorem is proved for (1 + ε)-quasimöbius mappings in Rn. © 2018 Sobolev Institute of Mathematics.
