changed the statement 2011-08-11 4c15ebf
LaTeX: \Ob

	Introduced a macro

	\def\Ob{\mathop{\rm Ob}\nolimits}

	and replaced any occurence of \text{Ob}( with \Ob(. There are
	still some occurences of \text{Ob} but these are sets, not the
	operator that takes the set of objects of a category.

Kernels of localization functors

	It turns out that for a multiplicative system in a additive
	category it is easy to determine the "kernel" of the
	localization functor. This then trickles down all the way to the
	case of the localization of a triangulated category.
