1ON HARMONIC MAPS INTO SYMPLECTIC GROUPS Sp(N)显示文摘By means of the theory of harmonic maps into the unitary group U(N), the authors study harmonic maps into the symplectic group Sp(N). The symplectic uniton and symplectic ex--tended uniton are introduced. The method of the symplectic Backlund transformation and the Darboux transformation is used to construct new symplectic unitons from a known one.HEQUN SHENYIBING 2001Chinese Annals of Mathematics,Series B2001,22,4:5
2EXPLICIT CONSTRUCTION FOR HARMONIC SURFACES IN U(N) VIA ADDING UNITONS显示文摘The authors give an algebraic method to add uniton numbers for harmonic maps from a simply connected domain ? ? R2∪{∞} into the unitary group U(N) with ?nite uniton number. So, it is proved that any n-uniton can be obtained from a 0-uniton by purely algebraic operations and integral transforms to solve the ?ˉ-problem via two different ways.HEQUN SHENYIBING 2004Chinese Annals of Mathematics,Series B2004,25,1:3
3ON PSEUDO-HOLOMORHPIC CURVESIN COMPLEX GRASSMANNIANS显示文摘Further geometry and topology for pseudo-holomorphic curves in complex Grassmannians Gm(CN) are studied. Some curvature pinching theorems for pseudo- holomorphic curyes with constant Kahler angles in Gm(CN) are obtained, so that the corresponding results for pseudoholomorphic curves in complex projective spaces are generalized.SHENYIBING DONGYUXING 1999Chinese Annals of Mathematics,Series B1999,20,3:1
4LOOP GROUP ACTIONS AND THE RIBAUCOUR TRANSFORMATIONS FOR FLAT LAGRANGIAN SUBMANIFOLDS显示文摘The Ribaucour transformations for flat Lagrangian submanifolds in Cn and CPn via loop group actions are given. As a consequence, the authors obtain a family of new flat Lagrangian submanifolds from a given one via a purely algebraic algorithm. At the same time, it is shown that such Ribaucour transformation always comes with a permutability formula.XIAQIAOLING SHENYIBING 2005Chinese Annals of Mathematics,Series B2005,26,3:0
