Putting String/string Duality to the Test
After simultaneous compactification of spacetime and worldvolume onK3, theD = 10 heterotic fivebrane with gauge group SO(32) behaves like a D = 6 heterotic string with gauge group SO(28)× SU(2), but with Kac–Moody levels different from those of the fundamental string. Thus the string/fivebrane duality conjecture in D = 10 gets replaced by a string/string duality conjecture in D = 6. Since D = 6...
متن کاملString-string Duality in Ten Dimensions
The heterotic string occurs as a soliton of the type I superstring in ten dimensions, supporting the conjecture that these two theories are equivalent. The conjecture that the type IIB string is self-dual, with the strong coupling dynamics described by a dual type IIB theory, is supported by the occurrence of the dual string as a Ramond-Ramond soliton of the weakly-coupled theory.
متن کاملTopological Partition Function and String-String Duality
The evidence for string/string-duality can be extended from the matching of the vector couplings to gravitational couplings. In this note this is shown in the rank three example, the closest stringy analog of the Seiberg/Witten-setup, which is related to the Calabi-Yau WP 4 1,1,2,2,6(12). I provide an exact analytical verification of a relation checked by coefficient comparison to fourth order ...
متن کاملM-Theory and String-String Duality
In this article we examine the compatibility of some recent results, results relating M-Theory to String Theory, with the string-string duality conjecture in six-dimensions. In particular, we rederive the relation between M-Theory and Type IIA strings. We then go on to examine in detail M-Theory on K3× S and its relation to the Heterotic theory on T . We conclude with some remarks on M-Theory o...
متن کاملCosmological Quantum String Vacua and String-String Duality
Implications of string-string dualities to cosmological string vacua are discussed. Cosmological vacua of classical string theories comprise of disjoint classses mapped one another by scale-factor T-duality. Each classes are, however, afflicted with initial/final cosmological singularities. It is argued that quantum string theories and string-string dualities dramatically resolve these cosmolog...
