Semigroups of shift register counting matrices. (English) Zbl 0790.20086
Summary: This is a revised and corrected version of notes from lectures by Andrew Gleason. The goal of the paper is a structure theorem about “onto maps” from the space of infinite Boolean sequences to itself, induced by binary functions on a shift register. The methods of proof involve a close study of the semigroup of counting matrices.
