摘要
Triangular deformation of the orthosymplectic Lie superalgebra osp(1\4) is defined by chains of twists. The corresponding classical r-matrix is obtained by a contraction procedure from the trigonometric r-matrix. The carrier space of the constant r-matrix and the twist element is the Borel subalgebra. The known super-Jordanian twist of osp(1\2) is generalized as an extended twist to the orthosymplectic Lie superalgebras of higher rank. The dimension of the cobracket kernel is related to the number of generators with primitive twisted coproduct of the deformed algebra.
