Wed, 26 Jan 2011 14:13:18 +0000 zhang Just checkin
Wed, 26 Jan 2011 14:12:36 +0000 zhang Small modification
Wed, 26 Jan 2011 13:21:16 +0000 zhang ok
Tue, 25 Jan 2011 12:14:31 +0000 zhang 1. Myhill.thy is proved to correct some typos. 2. Some sections are added to the first direction. 3. The small theory of list difference is now separated into Prefix_subtract.thy and the ROOT.ML
Mon, 24 Jan 2011 11:29:55 +0000 zhang Directory [tphols-2011] is added to host the commented version of [Myhill.thy]. Directory [pres] is created to host a build session for logical image [ListP] which is essentially [Main] extended with [List_prefix.thy].
