  • Extremal quasiconformality vs bounded rational approximation 
    Krushkal, S.L. (Український математичний вісник, 2019)
    We show that, on most of the hyperbolic simply connected domains, the weighty bounded rational approximation in a natural sup norm is possible only for a very sparse set of holomorphic functions (in contrast to the integral ...
  • Hyperbolic metrics on universal Teichmüller space and extremal problems 
    Krushkal, S.L. (Український математичний вісник, 2011)
    The paper consists of two parts, both related to complex geometry of the universal Teichm¨uller space. We reprove that all contractible invariant metrics on this space coincide and apply this important fact to solving the ...
