摘要：
The exponential integral function (EIF) and the generalized exponential function (GEIF) are defined as E(x,y) = integral(infinity)(1) e(-xu)u(-y) du and G(x,y,z) = 1/Gamma(z + 1) integral(infinity)(1) e(-xu)u(-y) (lnu)(2) du, respectively. In this paper, uniform convergences of the EIF and the GEIF are investigated. We also study the continuity differentiability and asymptotic behaviour of these functions.
