Quantization of the Lie superalgebra of Witt type.

In this paper, we use the quantization technique by a Drinfel'd twist to quantize the Lie superalgebra of Witt type, whose Lie super-bialgebra structures were recently determined by Yue and Zhu, and we obtain a new class of non-commutative and non-cocommutative Hopf superalgebras.
