Announcing two abstracts

An abstract of my proposed talk for next month's CT04 at UBC Vancouver has just been put up at http://fej.math.wes.home.att.net/CT04-Abstract.htm . My talks at Union College, Bangalore, and Calcutta last November, December, and January, respectively, are abstracted in the item http://b.mikolajewska.home.att.net/text/SIPRfejAbstrct.htm , which also provides links to two browser-optimized versions (one for Netscape, one for MSIE; I hope that other browsers will find that at least one of these renders acceptably) of a uniform write-up of what I had to say at those events. Comments, suggestions, errata, broken HTML? Please call these all to my attention. Thanks. -- F.E.J. Linton (Math/CS, Wesleyan U., Middletown, CT 06459 USA)
