Abstract:We are defining the trigonometric Lie subalgebras in
$$bar X_infty   = bar A_infty  (bar B_infty  ,bar C_infty  ,bar D_infty  )$$
which are the natural generalization of the well known Sin-Lie algebra. The embedding formulas into
$$bar X_infty  $$
are introduced. These algebras can be considered as some Lie algebras of quantum tori. An irreducible representation ofA, B series of trigonometric Lie algebras is constructed. Special cases of the trigonometric Lie factor algebras, which can be considered as a quantum (preserving Lie algebra structure) deformation of the Kac-Moody algebras are considered.
