another Bug in Reduce ?
Dear group, in message <dba4l5$elr$1 at smc.vnet.net> (07/16 2005), Mukhtar Bekkali described a problem which involved Root[.] in dependance of a parameter. This revealed another difference in the Reduce algorithms of versions 5.1 and 5.2. Please have a look at http://people.freenet.de/Peter_Berlin/Mathe/ReduceBug/ReduceBug.nb or http://people.freenet.de/Peter_Berlin/Mathe/ReduceBug/ReduceBug.html. In this case, version 5.1 did the better Job (and faster too). Peter P.S. the strange looking test for the root being real became necessary, because Im[#]==0& did not work.
