In this letter, a new loop algebra G is constructed, from which a new isospectral problem is established. It follows that integrable couplings of the well-known
Generalizing the idea involved in a previous paper [Commun. Theor. Phys. (Beijing, China) 41 (2004) 685], “quantity in phase space” is introduced. Thus starti
Based on relativistic constituent quark (RCQ) model, the electric and magnetic form factors are analyzed.The ratio of the two form factors for the proton G Ep/
A newly transparent approach for determining energy eigenvalues is proposed, which is finding the ‘eigen-operator' of the square of the Schroedinger operat
