- Melih> Here are my questions...
- Melih> 1- Where can I find an explicit proof of this and related theorems?
- Melih> (In Porteus' (Topological Geometry) , there is some info about the subject
- Melih> but if there other sources, I'd like to know them.)
-
- Melih> 2- Is this theorem valid only for finite dimensional case?
- Melih> (i.e. Is there an infinite dimensional real divison algebra?)
-
- Melih> Thanks for any information ....

- Melih, Look at "Studies in Modern Algebra" edited by A. A. Alber, MAA
- Studies in Mathematics vol. 2, published by the Math. Assoc. of
- America. There is an article by Charles W. Curtis in there entitled
- the "Four and Eight Square Problem and Division Algebras".
