Hydrodynamic normalization conditions in the theory of degenerate Beltrami equations

We study the existence of normalized homeomorphic solutions for degenerate Beltrami equation fz = μ(z )f in whole complex plane C , assuming that its measurable coefficient ), | ) |<1 a. e., has compact support and degeneration is controlled by tangential dilatation quotient KT μ (z z0) . show if bounded or finite mean oscillation dominants, satisfies Lehto type integral divergence condition, then admits a regular W1,1loc solution f with hydrodynamic normalization at infinity. also give criteria Calderon-Zygmund Orlicz types terms maximal Kμ
