The ~rivero university pages
1990s onward · Surviving references
The historical personal address was dftuz.unizar.es/~rivero/. The launch of Conjeturas explicitly links it as my longstanding homepage. Its research, politics, teaching and bicycle-project branches help recover a much broader site than a publication list.
Colin McLarty forwarded my sci.math question to the Categories mailing list: could the generalized spaces of topos theory be related to Connes' noncommutative spaces? The concrete example was the Kronecker foliation of the two-dimensional torus. The quotation preserves the addresses rivero@cc.unizar.es and rivero@sol.cie.unizar.es.
This is related contemporary material for the chronology's sheaves and noncommutative-geometry entries. The forward does not establish which of their original message identifiers it matches; those records remain separate.
The newsgroup creation result lists Alejandro Rivero, at rivero@sol.cie.unizar.es, among the YES voters. The proposal passed 365 to 26. The date is that of the published result, not the individual vote.
A proposal to place a map behind ordinary HTML links, retaining text-browser access and avoiding a server round trip. Alex Hopmann's reply preserves the original question and its date.
A signed contribution from rivero@dftuz.unizar.es to the university's 1995 feedback page: abandoned web pages, and a request for an “Every OS” option in the operating-system menu.
Ka-Ping Yee's reply preserves my explanation of the real-time implementation and its performance limits. It also names PAPER224.html, a further item to recover from the old wwwlab tree.
The proposal to expose incoming links through LINK relationships in a document's HEAD. The message carries its original sol.unizar.es signature and links the experimental wwwlab page.
An IETF HTTP working-group message about negative preferences in content negotiation: accepting a wildcard family while rejecting a particular subtype.
A promoter-group list reproduced in Andreu Veà's 2002 history of the Internet identifies Alejandro Rivero as a systems integrator at Telefónica I+D and records arivero@tid.es.
2007 and 2018 recollections · Retrospective sources
The Internet en Aragón history project names me in connection with the university server and gives 20 December 1993. A later newspaper interview recalls the department's NeXT machines and early browsing. These are retrospective sources, not pages published in 1993.
An early econophysics bibliography and companion draft about ownership, monetary scale, arbitrage and fixed points. The surviving pages identify Zaragoza and Telefónica I+D; an exact original publication date has not yet been recovered.
The old research page also preserves bibliographic experiments: iterated references and a chronology of noncommutative geometry. It records how the website itself was used as a research tool.
