On the Markoff spectrum on the Hecke group of index six
Byungchul Cha, Dong Han Kim, Deokwon Sim
The discrete part of the Markoff spectrum on the Hecke group of index 6 was determined by A.~Schmidt. In this paper, we study its Markoff and Lagrange spectra after the smallest ac…
The Markoff and Lagrange spectra on the Hecke group H4
Dong Han Kim, Deokwon Sim
We consider the Markoff spectrum and the Lagrange spectrum on the Hecke group . They are identical to the Markoff and Lagrange spectra of the unit circle. The Markoff…
The spectrum of the exponents of repetition
Deokwon Sim
For an infinite word , Bugeaud and Kim introduced a new complexity function which is called the exponent of repetition of . They sh…
Quasi-Sturmian colorings on regular trees
Dong Han Kim, Seul Bee Lee, Seonhee Lim +1
Quasi-Sturmian words, which are infinite words with factor complexity eventually share many properties with Sturmian words. In this paper, we study the quasi-Sturmian colorin…
