Issue Date: | 2014 | Journal: | Journal of Convex Analysis | Abstract: | We define the quasi-gamma functions as the functions f :]0, infinity[->]0, infinity[ such that f(1) = 1, f(x + 1) = x f(x) for every x > 0, and f is quasi-convex. The main example of quasi-gamma function is the gamma function defined by Euler. We study some properties of the quasi-gamma functions and of the class Q of these functions. | URI: | http://hdl.handle.net/10553/73218 | ISSN: | 0944-6532 | Source: | Journal Of Convex Analysis [ISSN 0944-6532], v. 21 (3), p. 765-783, (2014) |
