Logarithmic Asymptotics of the Nonlinear Cauchy–Riemann–Beltrami Equation

  • Published:
Ukrainian Mathematical Journal Aims and scope

We study regular solutions of the nonlinear Cauchy–Riemann–Beltrami equation for the logarithmic asymptotics in terms of the lower limits and solve an extreme problem for the functional disk image area in a certain class of solutions to the nonlinear Cauchy–Riemann–Beltrami system.
