A note on the perturbations of subshifts
Haritha Cheriyath
In this paper, we consider different classes of subshifts and study their perturbations obtained by forbidding sequences that contain a given word as a subword. We show that the pe…

Asymptoticity, automorphism groups and strong orbit equivalence
Haritha Cheriyath, Sebastián Donoso
Given any strong orbit equivalence class of minimal Cantor systems and any cardinal number that is finite, countable, or the continuum, we show that there exists a minimal subshift…

On Escape rate for subshift with Markov measure
Nikita Agarwal, Haritha Cheriyath, Sharvari Neetin Tikekar
In this paper, we consider a subshift of finite type with Markov measure. By considering a union of cylinders as holes, we investigate the exponential growth rate of measure of poi…
