TWISTED YANGIANS, DRINFELD APPROACH

摘要

Following V. G. Drinfeld's approach, the twisted Yangian for a basic Lie superalgebra is defined as Manin's quadruple quantization. The Yangian of a strange Lie superalgebra of Q_n type as an example of such a Yangian is described. The current system of generators and defining relations is obtained. The construction of a quantum double is discussed.
