Ismagil Habibullin, Kostyantyn Zheltukhin, Marina Yangubaeva

摘要:

研究了对应于半单或仿射李代数的Cartan矩阵的微分-差分可积指数型系统。对于$A_2$,$B_2$,$C_2$,$G_2$等代数所对应的系统,给出了两个方向的积分完备集,对于经典级数$A_N$,$B_N$,$C_N$的单李代数和级数$D^{(2)}_N$的仿射代数,给出了相应的系统的Lax表示.

英文摘要:

Differential-difference integrable exponential type systems are studied corresponding to the Cartan matrices of semi-simple or affine Lie algebras. For the systems corresponding to the algebras $A_2$, $B_2$, $C_2$, $G_2$ the complete sets of integrals in both directions are found. For the simple Lie algebras of the classical series $A_N$, $B_N$, $C_N$ and affine algebras of series $D^{(2)}_N$ the corresponding systems are supplied with the Lax representation.
