Real Hamiltonian forms of affine Toda field theories: spectral aspects

Vladimir S. Gerdjikov, Georgi G. Grahovski, Alexander A. Stefanov

The paper is devoted to real Hamiltonian forms of 2-dimensional Toda field theories related to exceptional simple Lie algebras, and to the spectral theory of the associated Lax ope…

Recursion operators and the hierarchies of MKdV equations related to $D_{4}^{(1)}$ , $D_{4}^{(2)}$ and $D_{4}^{(3)}$ Kac-Moody algebras

V. S. Gerdjikov, A. A. Stefanov, I. D. Iliev +4

We constructed the three nonequivalent gradings in the algebra $D_{4} ≃ so (8)$ . The first one is the standard one obtained with the Coxeter automorphism $C_1=S_{α_2} S_{α_1}S_{α…

New types of two component NLS-type equations

Vladimir S. Gerdjikov, Alexander A. Stefanov

We study MNLS related to the D.III-type symmetric spaces. Applying to them Mikhailov reduction groups of the type $Z_{r} \times Z_{2}$ we derive new types of 2-compone…
