An infinite word is -automatic if, for all , its st letter is the output of a deterministic automaton fed with the representation of in the considered numeration system . In this extended abstract, we consider an analogous definition in a multidimensional setting and present the connection to the shape-symmetric infinite words introduced by Arnaud Maes. More precisely, for , we state that a multidimensional infinite word over a finite alphabet is -automatic for some abstract numeration...
