Feb 28, 2010 at 21:58 comment added kakaz I mean straight thing: to have subsystem which is equivalent (homeomorphic?) to some "minimal subset of PA". From my point of view interesting part is: what is "minimal subset of PA" which allows UTM construction. My intention was to check, if You have some model ( in fact some real mathematic system) what class of "reasonable theories" allow You to axiomatize it. But it seems to be too broad, exactly as in Your question;-)
Feb 28, 2010 at 20:34 comment added Anton Petrunin Main question is what do you mean by "embedding" Practically any dynamical system can be can be "embedded" (in some sense) in a shift space (and I do not want it to be "alive").
