Abstract
The following four conjectures about structural properties of SAT are studied in this paper. (1) SAT ∈P SPARSE∩NP; (2) SAT ∈SRTD tt; (3) SAT ∈P bAPP tt ; (4)FP SAT tt . It is proved that some pairs of these conjectures implyP=NP, for example, if\(SAT \in P^{SPARSE \cap NP} \) and SAT ∈p bAPP tt , or if SAT ∈SRTD tt and SAT ∈P bAPP tt , thenP=NP. This improves previous results in literature.
