Simplicial constructions in the K-theory of exact categories
We specify simplicial and categorical constructions used to define the
K-theory space for a given exact category. Using the G-construction,
we deduce a Grothendieck style presentation for K_1 by generators and
relations. Invariants of quadratic forms with values in K-groups in
the categorical setting will be also discussed, if time remains.
