the gradient function is |x|^p-2 x
and i need to find the function, which apparently is 1/p |x|^p but i can't figure out how to show this.
This is for a bigger problem where the function must be convex. and also p>1
I tried, finding the derivative of 1/p |x|^p , but i don't get the gradient function.
At first, I thought about this function: 1/p-1 |x|^p-1 where you can easily get the gradient function by taking the derivative but i was told that this is not a convex function.
any help would be greatly appreciated.
