Définition(s)

In mathematics, the beta function, also called the Euler integral of the first kind, is a special function that is closely related to the gamma function and to binomial coefficients. It is defined by the integral

${\\displaystyle \\mathrm {B} (z_{1},z_{2})=\\int _{0}^{1}t^{z_{1}-1}(1-t)^{z_{2}-1}\\,dt}$

for complex number inputs
${\\displaystyle z_{1},z_{2}}$ such that ${\\displaystyle \\Re (z_{1}),\\Re (z_{2})>0}$ .
