Those identities will hold when k ∈ $$ \mathbb{N} $$ and p∈ $$ \mathbb{C} $$ (I had already proved that). if you replace to different complex values like -1, $$ \frac{1}{2}$$... you'll get some other cool identities.

My question is I don't know how to google this big, complex staff to make sure if it had been found.
