Here F(2) is the famous Richard Thompson's group usually denoted by $F$. We find the growth rate of the monoid of positive words in $F(p)$ and show that it does not exceed $p+1/2$. Also we describe new normal forms for elements of $F(p)$ and, using these forms, we find a lower bound for the growth rate of $F(p)$ in its natural generators. This lower bound asymptotically equals $(p-1/2)\\log_2 e+1/2$ for large values of $p$.", "revisions": [ { "version": "v1", "updated": "2005-11-18T21:32:04.000Z" } ], "analyses": { "subjects": [ "20F32", "05C25" ], "keywords": [ "growth rate", "positive words", "lower bound asymptotically equals", "famous richard thompsons group" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math.....11474B" } } }
