| Summary: | The relationship between solutions of the sinh-Laplace
equation and the determination of various kinds of
surfaces of constant Gaussian curvature, both positive
and negative, will be investigated here. It is shown
that when the metric is given in a particular set
of coordinates, the Gaussian curvature is related to
the sinh-Laplace equation in a direct way. The
fundamental equations of surface theory are found to
yield a type of geometrically based Lax pair for the system.
Given a particular solution of the sinh-Laplace
equation, this Lax can be integrated to determine
the three fundamental vectors related to the surface.
These are also used to determine the coordinate vector
of the surface. Some specific examples of this procedure
will be given. |
