| Abstract: | Booth and his co-authors have shown in 2], that many new approaches to theory revision (with fixed K) can be represented by two relations, < and
\vartriangleleft{{\vartriangleleft}}, where < is the usual ranked relation, and
\vartriangleleft{{\vartriangleleft}} is a sub-relation of < . They have, however, left open a characterization of the infinite case, which we treat here. |
