A family of formulas with reversal of high avoidability index
Currie, James; Mol, Lucas; Rampersad, Narad (World Scientific, 2017)We present an infinite family of formulas with reversal whose avoidability index is bounded between 4 and 5, and we show that several members of the family have avoidability index 5. This family is particularly interesting ... -
On avoidability of formulas with reversal
Currie, James D.; Mol, Lucas; Rampersad, Narad (EDP Sciences, 2018-02-13)While a characterization of unavoidable formulas (without reversal) is well-known, little is known about the avoidability of formulas with reversal in general. In this article, we characterize the unavoidable formulas ...
