Hopf Topology Archive

Welcome to the Hopf Topology Archive!

Hopf is undergoing updates of software and is not configured correctly yet. Full service is expected by the end of the weekend. Clarence Wilkerson, Friday 2:00PM

These are accessible as http://hopf.math.purdue/AuthorName <--- usually last names of authors. If you have a submission that has not been announced or posted and some time has elapsed, please email Mark and Clarence (but please try the "Reload" button on your browser first. Thanks, Clarence)

    Hopf has been upgraded to faster CPU and disk. Hope it helps the service. Also, HTTP uploading (http://hopf.math.purdue.edu/upload.php) has been added. Clarence

  • I found an undeveloped roll of Tri X from early 80's. Here are the scans. Write me if you can figure out when and where this was. Current thought is the UWO conference from 1981.

  • Some Details of the Archive

    Hopf is currently a desktop Pentium III. The web software is the Apache Web server. The FTP software is WU-FTPD. The pages are written in dynamic HTML, so you may need to frequently "reload" pages from one visit to the next to capture the current version. The archive is maintained by Clarence Wilkerson and support staff from the Purdue Mathematics Department.Purdue Math. Dept. Home Page. Clarence thanks Mark Hovey for his contributions to What's New! and Allen Hatcher for his help with webpage layout.

    The Photo Album


    Most of these photos were taken by Clarence Wilkerson and scanned from color prints. If you have photos you'd like to have included, please email Clarence Wilkerson. Likewise, if you have requests for particular people, e-mail Clarence.

  • Hints on Browsing The Archive

    Netscape and Microsoft Explorer seem to be the dominant browsers on PC's and Mac's, while Netscape is available for most workstations. Most of my checking has been done under Netscape on a Unix box.

    These pages are intentionally low tech and don't requre browser support for forms, tables, cookies, java, or javascript. The pages should be useful with Lynx over a slow link. FTP is still available but could be phased out due to security problems.

  • Policy on previous drafts of submissions

    New versions of files will be installed at the author's request. The older versions normally are put into directories labeled as "old" or some such, and by default are not readable to the web. If any question arises as to the content of previous drafts ( in eight years this has not happened! ), previous drafts can be made available.
