利用Euler函数计算了一类秩为1的纯非紧黎曼对称超空间X = G/K的Harish-Chandra c-函数,证明了它是亚纯的.与偶数情形相比,c-函数的极点被移到右半空间。我们导出了X上球超函数的完全渐近Harish-Chandra级数展开式。在单根的重数是偶数负数的情况下,对于不寻常的参数选择,它们具有作为Jacobi多项式的封闭表达式。
We compute the Harish-Chandra c-function for a generic class of rank-one purely non-compact Riemannian symmetric super- spaces X = G/K in terms of Euler functions, proving that it is meromorphic. Compared to the even case, the poles of the c-function are shifted into the right half-space. We derive the full asymptotic Harish-Chandra series expansion of the spherical superfunctions on X. In the case where the multiplicity of the simple root is an even negative number, they have a closed expression as Jacobi polynomials for an unusual choice of parameters.
