Jörg-Martin Jehle,Stefan Harrendorfd for groups presented in sections 3.3, 3.4, and 3.5, respectively. Nevertheless, we begin with structures which generalize topological spaces, namely pretopological spaces and filter convergence spaces, for two reasons. First, additive and grounded closure operators of concrete categories may be in

Joshua D. Freilich,Graeme R. Newmanre operators are equivalently described by (generalized functorial) factorization systems. The interplay between closure operators and preradicals which we have seen for .-modules in 3.4 extends to arbitrary categories; it is described by adjunctions which are (largely) compatible with the compositi

Thomas M. Halaszynski D.M.D., M.D., M.B.A.d has been the theme of many research papers (see the Notes at the end of this chapter). In many cases, closure operators offer themselves as a natural tool to tackle the problem. We concentrate here on results for those categories of topology and algebra where this approach proves to be successful.
