Re: boson calculus and half inter spin? huh?

I always thought bosons were integer spin. I also heard that you can't
get half integer spin out of combining integer spin components. OK, fine
but now I come accross a book that uses what it calls the Boson calculus
to get integer and also what seems to be half integer spin reps of of
su(2). What is going on here?

The book is "Lie Groups and Algebras with applications to Physics,
Geometry and Mechanics" by Sattinger and Weaver. It is on page 52
(middle to bottom of the page). 


There is significant literature on bosonization. You might look the term
up in scholar.google.com.
