In this paper, we study certain interesting and useful properties of incomplete ℵ-functions. The incomplete ℵ-function is an extension of the ℵ-function. We find several useful classical integral transforms of these functions. Further, we examine the fractional calculus with the incomplete ℵ-functions and point out several special cases. Finally, we give the applications of incomplete ℵ-functions in detecting glucose supply in human blood.

INTRODUCTION, DEFINITIONSSeveral authors have introduced and investigated the various special functions (see, eg, gamma function, beta function, Bessel function, Mittag-Leffler function, hypergeometric function, and Fox's H-function). They have also done the systematic study of these functions and also given the applications in engineering, applied sciences, etc.In the 18th century, Legendre 1 and P. Schlömilch introduced the incomplete gamma functions (IGFs) and Tannery (1882), F. E. Prym (1877), and M. Lerch gave the series representation of incomplete gamma function. After that several researchers work deeply on incomplete gamma functions.In 19th Century, by Südland et al 2,3 introduced and investigated the Aleph function, after that many authors established interesting results and also gave the potential applications in Physics, Applied Mathematics, and Engineering disciplines, etc.Recently, Srivastava et al 4 investigate and systematic study of the incomplete Pochhammer symbols and also introduced generalized incomplete hypergeometric functions (GIHF). They also discussed the integral representation, derivative formulas, Mellin-Barnes contour integral of these GIHF and also gave the potential applications in the field of communication theory, groundwater pumping model and probability theory.Very recently, Srivastava et al 5 introduce and investigate the incomplete H-functions and incompleteH-functions, which is the extension of Fox's H-function. They established decomposition formula, derivative formula, classical integral transforms, and fractional calculus and also gave some applications of the incomplete H-functions.Motivated by the ongoing research work on incomplete special functions, we introduce and investigate the incomplete Aleph (ℵ)-functions with the help of the IGFs and also correlate with the other special functions. We also find the classical Math Meth Appl Sci. 2020;43:5602-5614. wileyonlinelibrary.com/journal/mma
