4.7 Influence of the measure

The inclusion of a local measure term corresponding to tex2html_wrap_inline3019 was studied by Brügmann and Marinari [56, 57, 58]. This amounts to adding to the action a term of the form tex2html_wrap_inline3021, where o (v) is the number of 4-simplices containing a vertex v . \ For tex2html_wrap_inline3027, this seems to lead merely to a shift of the critical line. This setting has been revived recently by Renken [178Jump To The Next Citation Point In The Article, 177Jump To The Next Citation Point In The Article] in the context of a renormalization group analysis.
