The Connes-higson Construction Is an Isomorphism
Let A and B be separable C-algebras, B stable. We show that the Connes-Higson construction gives rise to an isomorphism between the group of unitary equivalence classes of extensions of SA by B, modulo the extensions which are asymptotically split, and the homotopy classes of asymptotic homomorphisms from SA to B.
متن کاملGraph isomorphism is polynomial
We show that the graph isomorphism problem is determined in a polynomial time. This is done by showing that that two graphs on n vertices are isomorphic if and only if a corresponding system of (4n− 1)n equations in n nonnegative variables is solvable. 2000 Mathematics Subject Classification: 03D15, 05C50, 05C60, 15A48, 15A51, 15A69, 90C05.
متن کاملSyntactic Isomorphism of CNF Boolean Formulas is Graph Isomorphism Complete
We investigate the complexity of the syntactic isomorphism problem of CNF Boolean Formulas (CSFI): given two CNF Boolean formulas φ(a1, . . . , an) and φ(b1, . . . , bn) decide whether there exists a permutation of clauses, a permutation of literals and a bijection between their variables such that φ(a1, . . . , an) and φ(b1, . . . , bn) become syntactically identical. We first show that the CS...
متن کاملGraph Isomorphism is not AC reducible to Group Isomorphism
We give a new upper bound for the Group and Quasigroup Isomorphism problems when the input structures are given explicitly by multiplication tables. We show that these problems can be computed by polynomial size nondeterministic circuits of unbounded fan-in with O(log log n) depth and O(log n) nondeterministic bits, where n is the number of group elements. This improves the existing upper bound...
متن کاملGraph Isomorphism is in the Low Hierarchy
The problem of determining whether two given finite graphs are isomorphic is easily seen to belong to the class NP. But up to now, no polynomial time algorithm is known. On the other hand, no NP-completeness proof is known either. That is, GRAPH ISOMORPHISM is one of the few “open problems” in NP according to Garey and Johnson’s terminology [9]. Note that GRAPH ISOMORPHISM is already mentioned ...
