Dejean's conjecture and letter frequency
We prove two cases of a strong version of Dejean's conjecture involving extremal letter frequencies. The results are that there exist an infinite " 5 4 + " -free word over a 5 letter alphabet with letter frequency 1 6 and an infinite " 6 5 + " -free word over a 6 letter alphabet with letter frequency 1 5 .
