“…B The Dibitetto-Petri flow in minimal N = 1 7d supergravity The solution discussed in section 6 was obtained in [6] taking the following ansatz: ds 2 7 = e 2U (r) ds 2 (AdS 3 ) + e 2V (r) dr 2 + e 2W (r) ds 2 (S 3 ), X = X(r), B In these expressions g and h are the gauge coupling of the vector fields 17 and the topological mass of the 3-form potential, respectively, of minimal N = 1 7d supergravity.…”

We establish a map between AdS 3 ×S 2 and AdS 7 solutions to massive IIA supergravity that allows one to interpret the former as holographic duals to D2-D4 defects inside 6d (1,0) CFTs. This relation singles out in a particular manner the AdS 3 ×S 2 solution constructed from AdS 3 ×S 3 ×CY 2 through non-Abelian T-duality, with respect to a freely acting SU(2). We find explicit global completions to this solution and provide well-defined (0,4) 2d dual CFTs associated to them. These completions consist of linear quivers with colour groups coming from D2 and D6 branes and flavour groups coming from D8 and D4 branes. Finally, we discuss the relation with flows interpolating between AdS 3 ×S 2 ×T 4 geometries and AdS 7 solutions found in the literature. 1 ylozano@uniovi.es 2

“…This provides a new scenario in which 2d (0,4) CFTs appear in string theory. 2d (0,4) CFTs play a key role in the microscopical description of 5d black holes with AdS 3 ×S 2 near horizon geometries [12][13][14][15][16][17]. In string theory they can be realised in D1-D5-KK systems [18][19][20][21] and D1-D5-D9 systems [22].…”

“…Conversely v, w are only linear functions away from localised sources -globally they need only be piecewise linear provided that the resulting δ-functions appearing in their second derivatives gives rise to a source corrected Bianchi identity, and this source is calibrated. Given the form of this expression it might be tempting to interpret a shift in v as coincident D8-D6 and D4-D2 bound states -however such configurations fail to obey the calibration condition discussed in the previous section at generic points along the interval -so cannot be used to glue solutions together without breaking supersymmetry 22 . Shifts in w on the other hand are different and give rise to something new.…”

“…These describe the near horizon limit of D1 and D5 branes intersecting with KKmonopoles [12][13][14][15] or D9-branes [16]. These systems play a prominent role in the microscopical description of five dimensional black holes [17][18][19][20][21][22]. 2d (4,0) CFTs are also central in the description of self-dual strings in 6d (1,0) CFTs, realised in M and F theory [23][24][25][26][27][28].…”

We study AdS 3 × S 2 solutions in massive IIA that preserve small N = (4, 0) supersymmetry in terms of an SU(2)-structure on the remaining internal space. We find two new classes of solutions that are warped products of the form AdS 3 ×S 2 ×M 4 ×R. For the first, M 4 =CY 2 and we find a generalisation a D4-D8 system involving possible additional branes. For the second, M 4 need only be Kahler, and we find a generalisation of the T-dual of solutions based on D3branes wrapping curves in the base of an elliptically fibered Calabi-Yau 3-fold. Within these classes we find many new locally compact solutions that are foliations of AdS 3 × S 2 × CY 2 over an interval, bounded by various D brane and O plane behaviours. We comment on how these local solutions may be used as the building blocks of infinite classes of global solutions glued together with defect branes. Utilising T-duality we find two new classes of AdS 3 × S 3 × M 4 solutions in IIB. The first backreacts D5s and KK monopoles on the D1-D5 near horizon. The second is a generalisation of the solutions based on D3-branes wrapping curves in the base of an elliptically fibered CY 3 that includes non trivial 3-form flux.

“…This line of research remains to be further exploited. See [81,82,83]. In particular it would be interesting to apply exact calculational techniques (see [84]) to the new classes of solutions, since this would provide for a deeper understanding of the IR regime of the different theories.…”

We review recent developments in the study of the AdS/CFT correspondence in lower dimensions. We start summarising the classification of AdS 3 ×S 2 solutions in massive Type IIA supergravity with (0,4) supersymmetries, and the construction of their 2d dual quiver CFTs. These theories are the seed for further developments, that we review next. First, we construct a new class of AdS 3 solutions in M-theory that describe M-strings in M5-brane intersections. Second, we generate a new class of AdS 2 ×S 3 solutions in massive IIA with 4 supercharges that we interpret as describing backreacted baryon vertices within the 5d N = 1 QFT living in D4-D8 branes. Third, we construct two classes of AdS 2 solutions in Type IIB. The first are dual to discrete light-cone quantised quantum mechanics living in null cylinders. The second class is interpreted as dual to backreacted baryon vertices within 4d N = 2 QFT living in D3-D7 branes. Explicit dual quiver field theories are given for all classes of solutions. These are used to compute the central charges of the CFTs, that are shown to agree with the holographic expressions.
