The Boolean Hierarchy I: Structural Properties [J. Cai et al., SIAM J. Comput ., 17 (1988), pp. 1232–252] explores the structure of the boolean hierarchy, the closure of NP with respect to boolean ... 
Intersection Suffices for Boolean Hierarchy Equivalence
TLDR
It is proved that these equalities hold for any complexity class closed under intersection, and that for any class C closed under union and intersection, the Boolean closure of C,The Boolean hierarchy over C, and the symmetric difference hierarchy overC all are equal. Expand
COMPLEXITY CLASSIFICATIONS FOR DIFFERENT EQUIVALENCE AND AUDIT PROBLEMS FOR BOOLEAN CIRCUITS
TLDR
For a number of restricted sets of gate types (bases) the authors obtain efficient algorithms, while for all other gate types it is shown these problems are at least NP-hard. Expand

This paper investigates a machine-based model for the complexity of approximating the CLIQUE problem. The model consists of nondeterministic polynomial time Turing machines with limited access to anExpand
Unambiguous Computation: Boolean Hierarchies and Sparse Turing-Complete Sets
TLDR
It is shown that two hierarchies---the Hausdorff hierarchy and the nested difference hierarchy---which in the NP case are equal to the Boolean closure fail to be equal for the UP case in some relativized worlds, and it is proved that closure under union is not needed for this claim. Expand

Structure of Complexity Classes: Separations, Collapses, and Completeness
During the last few years, unprecedented progress has been made in structural complexity theory; class inclusions and relativized separations were discovered, and hierarchies collapsed. We surveyExpand
A survey on counting classes
TLDR
The authors prove P/sup EP(log)/ 25 PP, investigate the Boolean closure BC( EP) of EP, and give a relativization principle which allows them to completely separate BC(EP) in a suitable relativized world and to give simple proofs for known relativizing results. Expand

This paper surveys basic results on complexity classes of partial multivalued functions. We stress basic inclusion relations, interesting hierarchies, and results that demonstrate that hierarchiesExpand
On the Power of Parity Polynomial Time
This paper proves that the complexity class ⊕P, parity polynomial time [PZ83], contains the class of languages accepted by NP machines with few accepting paths. Indeed, ⊕P contains a broad class ofExpand
On High and Low Sets for the Boolean Hierarchy
The polynomial-time hierarchy (PH) is central for many considerations of complexity theory. We call a set A 2 NP high (low, resp.) for the class p k of the polynomial-time hierarchy if p kExpand
