We enlarge the dictionary between matrix models for long linear quivers preserving eight supercharges in $d=5$ and $d=3$ and type IIB supergravity backgrounds with AdS$_{d+1}$ factors. We introduce mass deformations of the field theory that break the quiver into a collection of interacting linear quivers. which are decoupled at the end of the RG flow. We find and solve a Laplace probl... https://www.bekindtopets.com/mega-super-Thread-Sequins-Embroidered-Georgette-p6797-mega-pick/
