Instanton Moduli and Compactification
1.2. Primer on Connections. Recall from Peng’s talk that a connection on P → X can be thought of in three ways: (1) As a field of horizontal subspaces: TpP = HpP⊕VpP , where V P = ker (π∗). (Note that Vp ∼= g, and Hp ∼= Tπ(p)X). (2) As a g-valued 1-form A ∈ ΩX (g) which is invariant w.r.t. the induced G-action on ΩX (g). (3) Given a representation of G on W , as a vector bundle connection on th...
متن کاملThe Dynamics of Small Instanton Phase Transitions
The small instanton transition of a five-brane colliding with one end of the S/Z2 interval in heterotic M -theory is discussed, with emphasis on the transition moduli, their potential function and the associated non-perturbative superpotential. Using numerical methods, the equations of motion of these moduli coupled to an expanding Friedmann-Robertson-Walker spacetime are solved including nonpe...
متن کاملInstanton Moduli and Brane Creation
We obtain new intersecting 5-brane, string and pp-wave solutions in the heterotic string on a torus and on a K3 manifold. In the former case the 5-brane is supported by YangMills instantons, and in the latter case both the 5-brane and the string are supported by the instantons. The instanton moduli are parameterised by the sizes and locations of the instantons. We exhibit two kinds of phase tra...
متن کاملInstanton corrected hypermultiplet moduli spaces
Instanton corrections recently played a prominent role both in the context of string cosmology (KKLT models) and particle physics model building. A setup where one might hope to understand these corrections using string dualities and supersymmetry constraints on the low energy effective action (LEEA) is type II string theory compactified on a Calabi-Yau threefold (CY3). In this case the LEEA is...
متن کاملInstanton Moduli and Topological Soliton Dynamics
It has been proposed by Atiyah and Manton [1] that the dynamics of Skyrmions in IR may be approximated by motion on a finite dimensional manifold obtained from the moduli space of SU(2) Yang-Mills instantons in IR. Motivated by this work we describe how similar results exist for other soliton and instanton systems. We describe in detail two examples for the approximation of the infinite dimensi...
