Nonlinear Sigma Model, Zakharov-Shabat Method, and New Exact Forms of   the Minimal Surfaces in $R^3$
  General formulas for the construction of exact solutions of the equation of the minimal surface in $R^3$, which appears in various physical problems, have been derived by the Zakharov-Shabat "dressing" method. Particular examples are considered.
