I just found out that there is this interesting book about fractional powers of operators.

Maybe it can be useful for our purposes. For example on can consider the infinite Carlemann-matrix of \( \exp \) to be an operator (which is the infinite version of our matrix power method). However I didnt have a look into the book yet, so I dont know what they for example say about uniqueness etc.
