摘要: Abstract Some fundamental questions about infinite-vertex (free) profinite semigroupoids are clarified, putting in evidence differences with the finite-vertex case. This is done examples of free generated by graph a subshift. It also proved that for minimal subshifts, infinite edges such form connected compact groupoid.
