From: Claudio Sacerdoti Coen Date: Tue, 26 Jul 2005 12:24:53 +0000 (+0000) Subject: **** Experimental: **** X-Git-Tag: V_0_7_2~67 X-Git-Url: http://matita.cs.unibo.it/gitweb/?a=commitdiff_plain;h=c12d08acf947823bbfd5909618b042c65ff107de;p=helm.git **** Experimental: **** After the disambiguation, if the term is no longer ambiguous, we forget the environment. In this way we are forced to do more work later (since we have less aliases), but we have more freedom (since we have less aliases) in the future disambiguations. --- diff --git a/helm/matita/library/Z/orders.ma b/helm/matita/library/Z/orders.ma index 60c727ceb..756d02271 100644 --- a/helm/matita/library/Z/orders.ma +++ b/helm/matita/library/Z/orders.ma @@ -27,18 +27,16 @@ definition Zle : Z \to Z \to Prop \def | (pos n) \Rightarrow match y with [ OZ \Rightarrow False - | (pos m) \Rightarrow (le n m) + | (pos m) \Rightarrow n \leq m | (neg m) \Rightarrow False ] | (neg n) \Rightarrow match y with [ OZ \Rightarrow True | (pos m) \Rightarrow True - | (neg m) \Rightarrow (le m n) ]]. + | (neg m) \Rightarrow m \leq n ]].
