Brane Constructions, Fractional Branes
, 1999
"... Compactifications of type IIB string theory on AdS5 ⊗ X5, where X5 is an Einstein space, can have onefourth or half maximal supersymmetry for certain choices of X5. Some of these theories admit exotic domain walls arising from 5branes wrapping 2cycles in X5. We explore the relationship among thes ..."

these domain walls, fractional branes and branes stretched on intervals. Worldvolume fluxes in the wrapped branes play an important role in the analysis. We draw some parallels between the AdS background with exotic domain walls and N = 1 supersymmetric MQCD, and identify other extended objects on the AdS
Fractional branes and wrapped branes
 J. High Energy Phys
, 1998
"... We discuss the “fractional Dbranes ” which arise in orbifold resolution. We argue that they arise as subsectors of the Coulomb branch of the quiver gauge theory used to describe both string theory Dbrane and Matrix theory on an orbifold, and thus must form part of the full physical Hilbert space. ..."

Fractional Branes and Dynamical Supersymmetry Breaking
, 2005
"... We study the dynamics of fractional branes at toric singularities, including cones over del Pezzo surfaces and the recently constructed Y p,q theories. We find that generically the field theories on such fractional branes show dynamical supersymmetry breaking, due to the appearance of nonperturba ..."

On the C n /Zm fractional branes
, 2008
"... We construct several geometric representatives for the C n /Zm fractional branes on either a partially or the completely resolved orbifold. In the process we use large radius and conifoldtype monodromies, and provide a strong consistency check. In particular, for C 3 /Z5 we give three different set ..."

The enhancon mechanism for fractional branes
"... We study the enhançon mechanism for fractional Dbranes in conifold and orbifold backgrounds and show how it can resolve the repulson singularity of these geometries. In particular we show that the consistency of the excision process requires that the interior space be not empty. In the orbifold cas ..."

Fractional branes on ALE orbifolds
, 2001
"... Abstract: We derive the classical type IIB supergravity solution describing fractional D3branes 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 ..."

In the process we use large radius and conifoldtype monodromies, and also check some of the orbifold quantum symmetries. We find the explicit Seibergdual ..."

Entropy of Anisotropic Universe and Fractional Branes

The entropy for the 3 or 4 charge fractional branes thus obtained is not of the expected form E 3 2 or E2. The expected form is realis ..."
