A new class of integrable surfaces associated with Bertrand curves Perline, Ron

Description

We present a new class of integrable surfaces associated with Bertrand curves. These surfaces are foliated by constant-torsion curves evolving according to a novel integrable geometric flow. Curves transverse to the constant-torsion curves (orbit curves) are Bertrand curves on the surface. The surfaces discussed interpolate two known integrable systems and we establish the connection. We also use tools from soliton theory to generate surface solutions using B\"{a}cklund transformations.
