Dyson’s “Favorite” Identity and Chebyshev Polynomials of the Third and Fourth Kind

George E. Andrews

Research output: Chapter in Book/Report/Conference proceedingChapter


The combinatorial and analytic properties of Dyson’s “favorite” identity are studied in detail. In particular, a q-series analog of the antitelescoping method is used to provide a new proof of Dyson’s results with mock theta functions popping up in intermediate steps. This leads to the appearance of Chebyshev polynomials of the third and fourth kind in Bailey pairs related to Bailey’s Lemma. The natural relationship with L.J. Rogers’s pioneering work is also presented.
