Factoring N=p^rq^s for Large r and s
Boneh et al. showed at Crypto 99 that moduli of the form N = pq can be factored in polynomial time when r ' log p. Their algorithm is based on Coppersmith’s technique for finding small roots of polynomial equations. In this paper we show that N = pq can also be factored in polynomial time when r or s is at least (log p); therefore we identify a new class of integers that can be efficiently fact...
متن کاملL-a N S (a )
Building self-maintaining overlay networks for locating information in a manner that exhibits locality-awareness is crucial for the viability of large internets. It means that costs are proportional to the actual distance of interacting parties, and in many cases, that load may be contained locally. This survey paper describes several locality-aware networks that support distributed content-bas...
متن کاملBis(μ-N-benzyl-N-furfuryldithiocarbamato)-1:2κ3 S,S′:S′;2:1κ3 S,S′:S′-bis[(N-benzyl-N-furfuryldithiocarbamato-κ2 S,S′)cadmium]
In the centrosymmetric title compound, [Cd(2)(C(13)H(12)NOS(2))(4)], pairs of dithio-carbamate ligands exhibit different structural functions. Each of the terminal ligands is bidentately coordinated to one Cd(II) atom and forms a planar four-membered CS(2)Cd chelate ring, whereas pairs of the tridentate bridging ligands link two neighbouring Cd(II) atoms, forming extended eight-membered C(2)S(4...
متن کاملBis(μ-N,N-dimethyldithiocarbamato-κ3 S,S′:S)bis[(N,N-dimethyldithiocarbamato-κ2 S,S′)copper(II)]
In the centrosymmetric dimeric title compound, [Cu(2)(C(3)H(6)NS(2))(4)], the Cu(II) atom is five-coordinate in a square-pyramidal environment. The basal coordination positions are occupied by four S atoms from two dimethyl-dithio-carbamate ligands and the apical coordination position is occupied by an S atom also bonded to the other Cu atom.
متن کاملAn $S$-adic characterization of minimal subshifts with first difference of complexity $1 \leq p(n+1) - p(n) \leq 2$
In [Ergodic Theory Dynam. System, 16 (1996) 663–682], S. Ferenczi proved that any minimal subshift with first difference of complexity bounded by 2 is S-adic with Card(S) ≤ 327. In this paper, we improve this result by giving an S-adic charaterization of these subshifts with a set S of 5 morphisms, solving by this way the S-adic conjecture for this particular case.
