评估了Nasrallah-Rahman和Barnes第二引理的q-积分的多维推广。这些是Jackson, Dougall,以及超几何级数的Pfaff-Saalschutz求和定理的积分类似。这些积分也可以写成特殊酉群上的群积分、紧辛群上的群积分或相应李代数上的共轭不变积分。
Multidimensional generalizations of a q-beta integral of Nasrallah–Rahman and Barnes’ second lemma are evaluated. These are integral analogues of Jackson, Dougall, and the Pfaff–Saalschutz summation theorem for hypergeometric series. These integrals can also be written as group integrals over the special unitary group, the compact symplectic groups or conjugation invariant integrals over the corresponding Lie algebras.
