Lectures on instantons
Stefan Vandoren, Peter van Nieuwenhuizen
This is a self-contained set of lecture notes on instantons in (super) Yang-Mills theory in four dimensions and in quantum mechanics. First the basics are derived from scratch: the…
Nonperturbative corrections to 4D string theory effective actions from SL(2,Z) duality and supersymmetry
Daniel Robles-Llana, Martin Rocek, Frank Saueressig +2
We find the D(-1) and D1-brane instanton contributions to the hypermultiplet moduli space of type IIB string compactifications on Calabi-Yau threefolds. These combine with known pe…
On de Sitter Vacua in Type IIA Orientifold Compactifications
Frank Saueressig, Ulrich Theis, Stefan Vandoren
This letter discusses the orientifold projection of the quantum corrections to type IIA strings compactified on rigid Calabi-Yau threefolds. It is shown that N=2 membrane instanton…
Membrane Instantons and de Sitter Vacua
Marijn Davidse, Frank Saueressig, Ulrich Theis +1
We investigate membrane instanton effects in type IIA strings compactified on rigid Calabi-Yau manifolds. These effects contribute to the low-energy effective action of the univers…
Gauging Conformal Algebras with Relations between the Generators
Kris Thielemans, Stefan Vandoren
We investigate the gauging of conformal algebras with relations between the generators. We treat the --algebra as a specific example. We show that the gauge-algebra is in…
