A Topological proof that $O_{2}$ is $2$ -MCFL

Subhadip Chowdhury

We give a new proof of Salvati's theorem that the group language $O_{2}$ is $2$ multiple context free. Unlike Salvati's proof, our arguments do not use any idea specific to two-dimen…

Ziggurat fringes are self-similar

Subhadip Chowdhury

We give explicit formulae for fringe lengths of the Calegari-Walker Ziggurats -- i.e. graphs of extremal rotation numbers associated to positive words in free groups. These formula…
