An arithmetic gamma function?

In some exercises I've stumbled upon a function which is denoted $\gamma_{m}(n)$ with m,n natural. I've no idea what is the definition of the function and could not infer from the exercises. Searching google yielded nothing, as it kept suggesting me the OTHER Gamma function.
Can anyone here help me please?

There is something called the incomplete gamma function which uses the symbol (lower case gamma) that you have, but it does look a little different.

elibj123,

Post some of the exercises. Perhaps someone will recognize it from the context.
