证明

Proving theorems in Coq is an interactive process: some decision procedures automate equational reasoning or Presburger arithmetic, for example, but most of the proofs consist in sequences of "tactics" entered by the user to guide Coq in resolving proof obligations.

在Coq中的证明定理是一个交互过程：比如部分判定过程可以自动完成等式推论或者Presburger算法，不过，更多的证明则是由用户输入用以指导Coq完成证明任务的tactics序列。

We analyse the Lewy theorem and the provement idea of the theorem, and find the equation (7)and (8)are not equivalent under the reversible transformation, this lead to the absurdity in the provement does not come into existence .

Although the localic Urysohn lemma was proved by Papert in 1958 early, and then Dowker and Papert improved this proof, but the localic Tietze extension theorem, which is stronger in form and is more convenient to be used, has not been proved for more than thirty years.

虽然Locale形式的Urysohn引理早在1958年即已由Papert证明，9年后Dowker和Papert又对此证明加以改进，但形式上更强、更便于应用的Locale形式的Tietze扩张定理却三十余年未获证明。
