The term “support” means different things in different parts of mathematics:
Given a function to a pointed object with the point playing the role of a zero element, then the support of is the subobject of on which is non-zero.
In topology the support of a continuous function as above is the topological closure of the set of points on which does not vanish:
If is a compact subspace, then one says that has compact support.
support = (-1)-truncation
