I'm interested in dynamical systems. More precisely, in the setting of actions of countable groups over zero-dimensional spaces. In particular my research focuses in the expansive case where these systems can be though of as sets of colorings of a countable group subject to a number of constrains. My research studies these objects -called subshifts- and describes them jointly in dynamical and computabilty terms. I give special attention to the case where these spaces can be defined by finitely many constrains.
