DOI: 10.1007/jhep05(2019)077
Abstract: A bstractWe discuss generalized partition function of 2d CFTs on thermal cylinder decorated by higher qKdV charges. We propose that in the large central charge limit qKdV charges factorize such that generalized partition function can… read more here.

DOI: 10.1007/jhep05(2025)049
Abstract: We synthesize and sharpen various observations about sub-AdS holography in the literature to associate a central charge to sub-AdS scales of AdS×X geometries. A key ingredient in our proposal is the idea that the AdS… read more here.
