A Bäcklund transformation of the restricted mKdV flow with a Rosochatius deformation is constructed. Its Lax representation and thus N invariants in involution are presented. Such Bäcklund transformation is a Rosochatius deformation of that of the restricted mKdV flow. 相似文献

报道了在系统搜寻稳定硅表面的过程中对四个稳定高指数表面Si(1，1，11)，(1，0，8)，(2，1，2)和(15，1，17)的低能电子衍射(LEED)图进行的分析和结果.这些表面经充分退火后都能给出属于各自表面的LEED图，而不是小面化的，说明它们都是稳定的.从它们的LEED斑点强度分布特征不仅可以推断(15，1，17)是主稳定表面，而(1，1，11)，(1，0，8)和(2，1，2)则是副稳定表面，还能知道这些副稳定表面的原胞结构特征，甚至许多重要细节.从原胞结构特征来看，这些副稳定表面有可能用作生长周期量子线的模板. 相似文献

Three novel finite-dimensional integrable Hamiltonian systems of Rosochatius type and their Lax representations are presented. We make a deformation for the Lax matrbces of the Neumann type, the Bargmann type and the high-order symmetry type of restricted cKdV flows by adding an additional term and then prove that this kind of deformation does not change the r-matrix relations. Finally the new integrable systems are generated from these deformed Lax matrices. 相似文献

We present an integrable sl(2)-matrix Camassa-Holm(CH) equation.The integrability means that the equation possesses zero-curvature representation and infinitely many conservation laws.This equation includes two undetermined functions,which satisfy a system of constraint conditions and may be reduced to a lot of known multicomponent peakon equations.We find a method to construct constraint condition and thus obtain many novel matrix CH equations.For the trivial reduction matrix CH equation we construct its N-peakon solutions. 相似文献
