From Fractional Branes
This is a pedagogical and extended version of the results published in Refs. [1, 2] and presented by the authors in various talks during the last year. We discuss the type II D-branes (both regular and fractional) of the orbifold R1,5 ⊗ R/Z2, we determine their corresponding supergravity solution and show how this can be used to study the properties of N = 2 super YangMills. Supergravity is abl...
متن کاملMore Anomalies from Fractional Branes 1
In this note we show how the anomalies of both pure and matter coupled N = 1, 2 supersymmetric gauge theories describing the low energy dynamics of fractional branes on orbifolds can be derived from supergravity.

متن کاملFractional space-like branes
We discuss construction and applications of instanton-like objects which we call fractional space-like branes. These objects are localised at a fixed point of a time-like (or more generally space-time) orbifold which is a string theoretical toy model of a cosmological singularity. We formulate them in boundary state, adsorption, and fermionisation approaches. 1 Fractional space-like branes in a...
متن کاملNon - extremal fractional branes †
We construct non-extremal fractional D-brane solutions of type-II string theory at the Z 2 orbifold point of K3. These solutions generalize known extremal fractional-brane solutions and provide further insights into N = 2 supersymmetric gauge theories and dual descriptions thereof. In particular, we find that for these solutions the horizon radius cannot exceed the non-extremal enhançon radius....
متن کاملFractional branes on ALE orbifolds
We derive the classical type IIB supergravity solution describing fractional D3-branes transverse to a C 2 /Γ orbifold singularity, for Γ any Kleinian ADE subgroup. This solution fully describes the N = 2 gauge theory with appropriate gauge groups and matter living on the branes, up to non-perturbative instanton contributions.
