Taimanov, Iskander A. Surfaces of revolution in terms of solitons. (English) Zbl 0896.53007 Ann. Global Anal. Geom. 15, No. 5, 419-435 (1997). In [Transl., Ser. 2, Am. Math. Soc. 179(33), 133-151 (1997; Zbl 0896.53006), see the preceding review], I. A. Taimanov considered the general case of modified Novikov-Veselov deformations. In the present paper, the global Weierstrass representation and its spectral properties are studied. The main result here states that for any \(u\geq 1\) the \(n\)th modified Korteweg-de Vries (mKdV) deformation transforms tori of revolution into tori of revolution, preserving their conformal types. As a consequence, the unit sphere and the round tori are stationary points of mKdV deformations. Two problems on invariance of first integrals of mKdV flows are discussed.
