K3–Fibrations and Heterotic-Type II String Duality
We analyze the map between heterotic and type II N=2 supersymmetric string theories for certain two and three moduli examples found by Kachru and Vafa. The appearance of elliptic j-functions can be traced back to specializations of the Picard-Fuchs equations to systems for K3 surfaces. For the three-moduli example we write the mirror maps and Yukawa couplings in the weak coupling limit in terms...
متن کاملHeterotic-Type II String Duality and the H-Monopole Problem
Since T-duality has been proved only perturbatively and most of the heterotic states map into solitonic, non-perturbative, type II states, the 6-dimensional string-string duality between the heterotic string and the type II string is not sufficient to prove the S-duality of the former, in terms of the known T-duality of the latter. We nevertheless show in detail that the perturbative T-duality,...
متن کاملDuality Between the Webs of Heterotic and Type II Vacua
We discuss how transitions in the space of heterotic K3×T 2 compactifications are mapped by duality into transitions in the space of Type II compactifications on Calabi–Yau manifolds. We observe that perturbative symmetry restoration, as well as non-perturbative processes such as changes in the number of tensor multiplets, have at least in many cases a simple description in terms of the reflexi...
متن کاملHeterotic/type-ii Duality and Its Field Theory Avatars
In these lecture notes, I will describe heterotic/type-II duality in six and four dimensions. When supersymmetry is the maximal N=4 it will be shown that the duality reduces in the eld theory limit to the Montonen-Olive duality of N=4 Super Yang-Mills theory. We will consider further compactiications of type II theory on Calabi-Yau manifolds. We will understand the physical meaning of geometric...
متن کاملHeterotic/Type II Duality in D=4 and String-String Duality
We discuss the structure of Heterotic/Type II duality in four dimensions as a consequence of string-string duality in six dimensions. We emphasize the new features in four dimensions which go beyond the six dimensional vacuum structure and pertain to the way particular K3 fibers can be embedded in Calabi-Yau threefolds. Our focus is on hypersurfaces as well as complete intersections of codimens...
