Abstract
A characterization of the two functions f ( x , y ) and g ( x , y ) in the ( f , g ) -inversion is presented. As an application to the theory of hypergeometric series, a general bibasic summation formula determined by such two functions f ( x , y ) and g ( x , y ) as well as four arbitrary sequences is obtained which unifies the bibasic summation formulas of Gasper and Rahman, Chu, and Macdonald. Furthermore, an alternative proof of the ( f , g ) -inversion derived from the ( f , g ) -summation formula is presented. A bilateral ( f , g ) -inversion containing Schlosser's bilateral matrix inversion as a special case is also obtained.

Over forty years have passed since the birth of the Constituent Quark Model, yet the scalar mesons still challenge theoreticians and experimentalists
An important problem is the understanding of the low energy part of the S-wave K −π + spectrum, where the existence of an I = 1/2 state, the κ(800) meson, has been the subject of a long-standing debate

Summary
Over forty years have passed since the birth of the Constituent Quark Model, yet the scalar mesons still challenge theoreticians and experimentalists. The BaBar Collaboration [6] uses the I = 1/2 elastic scattering amplitude from LASS for the K π S-wave Another approach is the non-parametric analysis of the K π amplitude from the D+ → K − K +π + decay performed by FOCUS [10]. Dalitz plot, applying the MIPWA technique, developed by the E791 Collaboration [12], to the same data set used for the K-matrix and Isobar fits [3]. The measured phase, in addition to the I = 1/2 K −π + phase, may contain contributions from the I = 3/2 components, as well as possible contributions from three-body final state interactions. The FOCUS spectrometer has a system of three multi-cell threshold Cerenkov counters to perform the charged particle identification, separating kaons from pions up to a momentum of 60 GeV/c. It is this interference with the P-wave that allows one to access the S-wave phase
