. Stirling's approximation is asymptotically equal to the factorial function for large values of n. It is possible to find a general formula for factorials using tools such as integrals and limits from calculus. A good solution to this is the gamma function. There are infinitely many continuous...
Recursive formulaGiven the above definition, it is straightforward to prove that the Gamma function satisfies the following recursion: ProofRelation to the factorial functionWhen the argument of the Gamma function is a natural number then its value is equal to the factorial of : ...

formula for the factorials. The so-called Gamma function is defined in Rudin [9] as follows: Definition 1.1. For 0 < x < ∞, Γ(x) :=∞ 0 t x−1 e −t dt. (1.2) But what does definition 1.1 mean? We are used to integrating over a closed interval [a, b], not...

MSC: Primary 33B15; 26A48; secondary 26D15; 26A51 Keywords: gamma function; Laplace transform; complete monotonicity; inequality 1 Introduction Stirling's formula √ n! ∼ 2π nnne–n (1.1) has important applications in statistical physics, probability theory and number theory. Due to its ...
The elliptic gamma function is a generalization of the Euler gamma function and is associated to an elliptic curve. Its trigonometric and rational degenerations are the Jackson q-gamma function and the Euler gamma function, respectively. The elliptic gamma function appears in Baxter's formula for ...
