Graduate Gamma function convergence of an integral

Click For Summary
The Gamma function converges for positive values of x and also for negative non-integer values, though this aspect is often overlooked in literature. To analyze convergence for negative non-integer values, the recursive formula for the Gamma function is recommended, as the integral representation does not apply in this case. The concept of analytic continuation allows the extension of the Gamma function beyond its initial domain, providing a broader understanding of its behavior. This approach clarifies the limitations of the integral representation for negative non-integer inputs. Overall, understanding these nuances is essential for accurate applications of the Gamma function in various mathematical contexts.

##\Gamma(x)=\int^{\infty}_0 t^{x-1}e^{-t}dt## converge for ##x>0##. But it also converge for negative noninteger values. However many authors do not discuss that. Could you explain how do examine convergence for negative values of ##x##.

I'm pretty sure it doesn't converge for negative noninteger values and that the formula is not applicable there. Use the recursive formula for the Gamma function instead to get those values.
 
There is a general concept called analytic continuation, where a function has a particular representation in some domain can be extended outside this domain.
