Abstract We 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 be rewritten in terms of auxiliary non-interacting bosons. The explicit expression for the generalized free energy is readily available in terms of the b... https://safeersappliancers.shop/product-category/bosch-dib091k50b-touch-control-90cm-island-cooker-hood-stainless-steel/
