The authors establish a set of fourteen character formulas in terms of Rβ and Rm functions. Folsom [6] studied character formulas and Chaudhary [5] expressed those formulas in terms of continued fraction identities. Andrews et al. [2] introduced multivariate R-functions, which are further classified as Rα; Rβ, and Rm (for m = 1, 2, 3, …) functions by Srivastava et al. [10].
