Description
Over the past few years so-called spindle solutions have received a lot of attention in the liturature. However, in most cases a clear holographic interpretation of these supergravity solutions remains absent. In this talk I will clarify various aspects of the landscape of spindle solutions. In particular, I will clarify a puzzle regarding the global symmetry of the disc solution dual to a class of Argyres-Douglas theories. In addition, when breaking supersymmetry I will show that spindle solutions in seven-dimensional gauged supergravity correspond to class S theories on the sphere with two locally $\mathcal{N}=1$ preserving punctures. Finally, I will show how a different global completion of the (local) spindle solution can describe holographic co-dimension two defects and explain what class of defect observables can be accessed using holography.
