Associated with an immersion φ: S3→CP3, we can define a canonical bundle endomorphism F : TS3→TS3 by the pull back of the Kahler form of CP3. In this article
Let M be a(2 k + 2 l + 2)-dimensional smooth manifold. For such M, Bande and Hadjar introduce a new geometric structure called contact pair which roughly is a c
Based on a 4 ×4 matrix spectral problem, an AKNS soliton hierarchy with six potentials is generated. Associated with this spectral problem, a kind of Riema
