Query: On Equistable, Split, CIS, and Related Classes of Graphs   We consider several graphs classes defined in terms of conditions on cliques
and stable sets, including CIS, split, equistable, and other related classes.
We pursue a systematic study of the relations between them. As part of this
study, we introduce two generalizations of CIS graphs, obtain a new
characterization of split graphs, and a characterization of CIS line graphs.
