 book: the theory of fractional powers of operators bo198214 Administrator Posts: 1,488 Threads: 95 Joined: Aug 2007 01/13/2009, 09:13 PM 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. Gottfried Ultimate Fellow Posts: 851 Threads: 126 Joined: Aug 2007 06/20/2010, 06:00 AM (This post was last modified: 06/20/2010, 06:00 AM by Gottfried.)
