Modules of Witt vectors

2005
Parallel to the construction of the (big or small) Witt vectors ring Λ(R) resp. W(p)(R) over a commutative ring R we construct a module L(A) and L(p, A) over Λ(R), resp. W(p)(R) if a graded R-algebra A is given.

Witt vectors which are rational functions

Communications in Algebra, 1993
One of the basic results proved by G. Almkvist asserts that K 0 EndP(A) ≈K 0(A) × A for any commutative ring A, where P(A) is the category of finitely generated projective modules over A and Ā 0 is the subring of the ring 1 + tA[[t]] = W(A) of Witt Vectors over A constituted by those elements of 1 + tA [[t ]] which represent rational functions.
