A resolution variant deciding some classes of clause sets,mechanisms may be defined to provide decision algorithms for other interesting classes of clause sets. We shall inquire along this line of arguments into extensions of the Maslov class (i.e. the class of formulas with prefix of type ?*?* and at most two literals in each disjunct) in a forthcoming paper.

Subclasses of quantified boolean formulas,ation problems for these classes are coNP-complete. These subclasses can be seen as extensions of Horn and 2-CNF formulas..Further it is shown that the evaluation problem for quantified CNF formulas remains PSPACE-complete, even if at most one universal variable is allowed in each clause.
