   Format: MarkdownItexWell, yes, but it is not the same, as the class S also denotes a corresponding class of SCFTs, not only POV of AGT, and there are many facts about each side not related to the correspondence. So many topics related to class S, like classification are not about AGT correspondence per se. Edit: are you in fact against keeping separate entries or just want to have them interlinked ?

   Format: MarkdownItexIt seems odd to vaguely refer to "a specific class of gauge field theories" and "certain superconformal field theories" while we have plenty of details on all this already.

   Format: MarkdownItexThe details in [[AGT correspondence]] are not describing the entire class $S$, it is stated in a special subcase. As Le Floch says > Class S is a wide class of 4d supersymmetric gauge theories (ranging from super-QCD (quantum chromodynamics) to non-Lagrangian theories) obtained by twisted compactification of 6d N=2 superconformal theories on a Riemann surface C. Or we have a more general description elsewhere in $n$Lab ?

   Format: MarkdownItexI mean, it is not only super-Yang-Mills case. Edit: of course, it is still a stub. But I will now skip an administrative duty because I have to explain a stub which is not finished yet. Please suggest changes and/or wait for completion.
