Limits of theory sequences over algebraically closed fields and applications
2004
Discrete Applied Mathematics
It provides an approach to build a new theory by the limit of some sequence of formal theories and also has potential applications to scientiÿc and engineering problems. ...
A computation model involving the computation of the limits of theory sequences is formally deÿned. It is called procedure scheme. ...
Why to study limits of theory sequences over algebraically closed ÿelds As we have seen, during its execution, Analysis has to determine for a given w i whether w i ∈ L(G i−1 ) or w i ∈ L(G i−1 ). ...
