Logarithmic Asymptotics of the Nonlinear Cauchy-Riemann-Beltrami Equation

摘要

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.
