摘要

Here, we establish a polynomial identity in three variables abc, and with the degree of the polynomial given in terms of two integers LM. By letting L and M tend to infinity, we get the 1993 Alladi–Gordon q-hypergeometric key-identity for the generalized Schur Theorem as well as the fundamental Lebesgue identity by two different choices of the variables. This polynomial identity provides a generalization and a unified approach to the Schur and Lebesgue theorems. We discuss other analytic identities for the Lebesgue and Schur theorems and also provide a key identity (q-hypergeometric) for Andrews’ deep refinement of the Alladi-Schur theorem. Finally, we discuss a new infinite hierarchy of identities, the first three of which relate to the partition theorems of Euler, Lebesgue, and Capparelli, and provide their polynomial versions as well.
