Abstract. In homotopy theory, exact sequences and spectral sequences
consist of groups and pointed sets, linked by actions. We prove that the
theory of such exact and spectral sequences can be established in a
categorical
setting which is based on the existence of kernels and cokernels with
respect
to an assigned ideal of null morphisms, a generalisation of abelian
categories
and Puppe-exact categories.
