Geometric Engineering of Quantum Field Theories
Sheldon Katz, Albrecht Klemm, Cumrun Vafa
Using the recent advances in our understanding of non-perturbative aspects of type II strings we show how non-trivial exact results for quantum field theories can be reduced…
BPS States of Exceptional Non-Critical Strings
A. Klemm, P. Mayr, C. Vafa
We study the BPS states of non-critical strings which arise for zero size instantons of exceptional groups. This is accomplished by using F-theory and M-theory duals and by employi…
New Higgs Transitions between Dual N=2 String Models
P. Berglund, S. Katz, A. Klemm +1
We describe a new kind of transition between topologically distinct type II Calabi--Yau vacua through points with enhanced non-abelian gauge symmetries together with fundamen…
Self-Dual Strings and N=2 Supersymmetric Field Theory
A. Klemm, W. Lerche, P. Mayr +2
We show how the Riemann surface of Yang-Mills field theory arises in type II string compactifications on Calabi-Yau threefolds. The relevant local geometry is given by fi…
Strong Coupling Singularities and Non-abelian Gauge Symmetries in String Theory
A. Klemm, P. Mayr
We study a class of extremal transitions between topological distinct Calabi--Yau manifolds which have an interpretation in terms of the special massless states of a type II string…
