On holographic duals of certain isolated weighted Gorenstein cDV singularities (2412.10698v1)

Abstract: Based on an important mathematical conjecture, together with hypothesis of homological mirror symmetry in the context of Landau-Ginzburg models, we show that a class of compound Du Val singularities do not admit a crepant resolution. Most of these singularities sit in the type cEn. This implies that those singularities are not dual to four dimensional N =1 superconformal quiver gauge theories through stacks of D3 branes placed at the singularities. We verify this statement on the physics side by enumerating consistent gauge theories.
