A. Gamma Function Fors>0define(1)Γ(s)=∫0∞ts−1e−tdt. Γis called thegamma function. Moreover, the gamma function extends to an holomorphic function in the half-plane{z∈C:Rez>0}, and is still given there by the integral formula(1). Furthermore, by Taylor expansion it has ...
Beta function and Gamma functionLaplace transformCombinatorial identityWe construct generating functions for beta-type rational functions and the beta polynomials. By using these generating functions, we derive a collection of functional equations and PDEs. By using these functional equations and PDEs, we...

Incomplete Beta Function Just as there are incomplete gamma functions, there is also an incomplete beta function, customarily defined for 0≤x≤1, p > 0(and, if x = 1, also q > 0) as (13.78)Bx(p,q)=∫0xtp−1(1−t)q−1 dt. Clearly, Bx=1(p,q) becomes the regular ...
Some properties such as transformation formulas, recurrence relations and integral representations are obtained for extended matrix functions. Generalised Gamma and Beta matrix functions are given as [3]: Γ(𝑃,𝑟)=∫∞0𝑡𝑃−𝐼𝑒(−𝑡−𝑟𝑡)𝑑𝑡,𝐵(𝑃,𝑄;𝑟)=∫...

We examined in parallel species richness and beta diversity components of nine taxonomic groups along a finite space, represented by pastured grasslands along an elevational gradient. Beta diversity, which is assumed to bridge local alpha diversity to regional gamma diversity was partitioned into the ...
