4.10 Non-spherical lattices

Alternative topologies for the underlying simplicial complex were considered by Bilke et al [51, 53]. They showed that for topologies tex2html_wrap_inline3067 and tex2html_wrap_inline2709, the free energy agrees to leading order with that of tex2html_wrap_inline2837 . Neither the critical value tex2html_wrap_inline3073, nor the leading contributions to the action density tex2html_wrap_inline3075 are changed. However, the simulations become more involved, since the size of the minimal configurations is increased.
