We derive in full detail the set of integral equations governing the decagonal and the dodecagonal solutions and identify them with the thermodynamic Bethe ansatz equations of the homogeneous sine-Gordon models. By evaluating the free energy in the conformal limit we compute the central charges, from which we observe general correspondence between the polygonal solutions in AdS n and generalized parafermions.journal articleSpringer2010-04application/pdfJournal of high energy physics420101081029-8479AA1188279Xhttps://tsukuba.repo.nii.ac.jp/record/21277/files/JHEP_2010-4.pdfeng10.1007/JHEP04(2010)108The original publication is available at www.springerlink.com© SISSA 2010
