Well, I would first check the references given in the Help file!. That's what they're for, no? Hastie's book is likely to more complete on the algebra, I think.

You might also be interested in the relevant chapters of Friedman, Hastie, et. al "The Elements of Statistical Learning Theory," which might be a gentler exposition of the math.

Of course, the code (or a suitable exposition of it, which may not exist) is the ultimate reference.
