Orbifolds of M-Theory and Type II String Theories in Two Dimensions
We consider several orbifold compactifications of M-theory and their corresponding type II duals in two space-time dimensions. In particular, we show that while the orbifold compactification of M-theory on T/J9 is dual to the orbifold compactification of type IIB string theory on T/I8, the same orbifold T /I8 of type IIA string theory is dual to Mtheory compactified on a smooth product manifold...
متن کاملExponentially Small Couplings between Twisted Fields of Orbifold String Theories
We investigate the natural occurrence of exponentially small couplings in effective field theories deduced from higher dimensional models. We calculate the coupling between twisted fields of the Z3 Abelian orbifold compactification of the heterotic string. Due to the propagation of massive Kaluza-Klein modes between the fixed points of the orbifold, the massless twisted fields located at these ...
متن کاملHeterotic and Type I String Dynamics from Eleven Dimensions
We propose that the ten-dimensional E8 × E8 heterotic string is related to an elevendimensional theory on the orbifold R × S/Z2 in the same way that the Type IIA string in ten dimensions is related to R × S. This in particular determines the strong coupling behavior of the ten-dimensional E8 × E8 theory. It also leads to a plausible scenario whereby duality between SO(32) heterotic and Type I s...
متن کاملOn the tenacity of cycle permutation graph
A special class of cubic graphs are the cycle permutation graphs. A cycle permutation graph Pn(α) is defined by taking two vertex-disjoint cycles on n vertices and adding a matching between the vertices of the two cycles.In this paper we determine a good upper bound for tenacity of cycle permutation graphs.
