This … WebA major conceptual step forward in understanding the logical architecture of living systems was advanced by von Neumann with his universal constructor, a physical device capable of self-reproduction. A necessary condition for a universal constructor to exist is that the laws of physics permit physical universality, such that any transformation (consistent with the …
WebIt entails that an existential theorem of T of the form (∃x ∈N)A(x) can be witnessed by a numeral n¯ such that T proves A(n¯). While NEP holds almost universally for natural intuitionistic set theories, the general existence property (EP), i.e. the property of a theory that for every existential theorem, a provably definable witness can ... Web1. The Myhill-Nerode theorem [1] gives yet characterisation of regular languages. It leads to a (non-constructive) definition of a minimal DFA that recognises a regular language …
