A transformation formula for a double basic hypergeometric series of type Φ0:2;21:2;2 is derived. This transformation yields a double series analogue of Sears’ transformation for a terminating 3Φ2 series. In the limit q→1, the formula reduces to a transformation for a terminating double Clausenian hypergeometric series of unit argument (one of the proper Kampé de Fériet series, F0:2;21:2;2(1,1)). This formula is a double series analogue of Whipple's terminating 3F2 transformation. This transformation gives rise to a transformation group (the invariance group) acting on the parameters of the double series. The invariance group is examined and shown to be a subgroup of a double copy of the symmetries of the square. 相似文献

We give elementary derivations of several classical and some new summation and transformation formulae for bilateral basic hypergeometric series. For motivation, we review our previous simple proof (Proc. Amer. Math. Soc. 130 (2002), 1103-1111) of Bailey's very-well-poised 6y6_6\psi_6 summation. Using a similar but different method, we now give elementary derivations of some transformations for bilateral basic hypergeometric series. In particular, these include M. Jackson's very-well-poised 8y8_8\psi_8 transformation, a very-well-poised 10y10_{10}\psi_{10} transformation, by induction, Slater's general transformation for very-well-poised 2ry2r_{2r}\psi_{2r} series, and Slater's transformation for general ryr_{r}\psi_{r} series. Finally, we derive some new transformations for bilateral basic hypergeometric series of a specific type. 相似文献

In this article we give a new transformation between elliptic hypergeometric beta integrals, which gives rise to a Weyl group
symmetry of type F
4. The transformation is a generalization of a series transformation discovered by Langer, Schlosser, and Warnaar (SIGMA 5:055,
2009). Moreover we consider various limits of this transformation to basic hypergeometric functions obtained by letting p tend to 0. 相似文献

In connection with estimation of interpolation orbits and coorbits we introduce a new transformation acting in the class of all parameter-space of real interpolation K-method. We “calculate” the result of the transformation of classical parameters. It is revealed that the transformation of weighted L1-spaces leads to Orlicz spaces. 相似文献

For i = 1,2, let Ai be a linear transformation on a complex vector space and let σ be a lattice isomorphism from the invariant subspace lattice of A1 onto the invariant subspace lattice of A2. We determine the conditions under which σ is implemented by a linear or conjugate linear transformation (or a sum of these two kinds). 相似文献

The Darboux transformation for the two dimensional A(2)2n-1 Toda equations is constructed so that it preserves all the symmetries of the corresponding Lax pair. The expression of exact solutions of the equation is obtained by using Darboux transformation. 相似文献

We construct a resolution of singularities for wave fronts having only stable singularities of corank 1. It is based on a transformation that takes a given front to a new front with singularities of the same type in a space of smaller dimension. This transformation is defined by the class Aµ of Legendre singularities. The front and the ambient space obtained by the Aµ-transformation inherit topological information on the closure of the manifold of singularities Aµ of the original front. The resolution of every (reducible) singularity of a front is determined by a suitable iteration of Aµ-transformations. As a corollary, we obtain new conditions for the coexistence of singularities of generic fronts. 相似文献

We introduce a non-linear injective transformation τ from the set of non-vanishing normalized Hausdorff moment sequences to the set of normalized Stieltjes moment sequences by the formulaT[(a n ) n=1 ∞ ] n = 1/a1 ...a n . Special cases of this transformation have appeared in various papers on exponential functionals of Lévy processes, partly motivated by mathematical finance. We give several examples of moment sequences arising from the transformation and provide the corresponding measures, some of which are related toq-series. 相似文献
