Suspension of a ring explained
In algebra, more specifically in algebraic K-theory, the suspension
of a
ring R is given by
[1]
where
is the ring of all infinite matrices with entries in
R having only finitely many nonzero elements in each row or column and
is its
ideal of
matrices having only finitely many nonzero elements. It is an analog of
suspension in
topology.
One then has:
