G_r,s量子群的对偶性

Duality for the G_r,s Quantum Group

Deepak Parashar, Roger J. McDermott

摘要:

双参数量子群G_r,s由五个元素生成,其中四个元素构成一个同构于GL_q(2)的Hopf子代数,而第五个生成元将G_r,s与GL_p,q(2)联系起来。我们明确地构造了G_r,s的对偶代数,并证明了它同构于gl(2)+ gl(1)的单参数变形,其中第二个参数出现在余结构中.我们还建立了G_r,s上的一个微分学,它提供了GL_p,q(2)上的微积分的一种实现.

英文摘要:

The two parameter quantum group G_r,s is generated by five elements, four of which form a Hopf subalgebra isomorphic to GL_q(2), while the fifth generator relates G_r,s to GL_p,q(2). We construct explicitly the dual algebra of G_r,s and show that it is isomorphic to the single parameter deformation of gl(2) + gl(1), with the second parameter appearing in the costructure. We also formulate a differential calculus on G_r,s which provides a realisation of the calculus on GL_p,q(2).
