Limit of Gamma Functions product


Recommended Posts

So, the application of this approximation to the Gamma function is independent of the number set that the argument of Gamma belongs to? i.e. wether the argument is natural or real number etc

 

Thank you!!!

I guess you can just apply the Stirling formula listed below to get the desired result.

 

[Remember that x!=Gamma(x+1)]

I don't think it has a wel defined limit. For large v, it will grow like v! (that is a factorial, not an exclamation).

 

Edit: Ack! I take that back. I missed the s^(-v/2) at the front, which is exponential decay. The exponential trumps the factorial, so I think the limit is 0.

 

Edit 2: Err... no, I think factorial trumps exponential, so now I am back to thinking it is infinite. Let's just check with mathematica..... and yes indeed it is infinite.

I found that the result depends on the value of s.

 

1. For 0<s<1, the result is infinity.

 

2. For s>1, the result is 0.

If s=1, the result is also 0.
