in the past, the Valuation Theory Home Page had been hosted by the department server of the Mathematics Department at the University of Saskatchewan, Saskatoon, Canada. We acknowledge the support we have received with gratitude.

We are very happy to announce that a mirror site of the Valuation Theory Home Page is also hosted by Kurt Gödel Research Center for Mathematical Logic at the University of Vienna, see
The Valuation Theory Home Page - Vienna site.

Please contact us if you have any suggestions for the reshaping and updating of the Valuation Theory Home Page at any of its two sites.

This web site is intended to be a forum for all mathematicians who work in valuation theory or apply valuation theoretical results in their own field of research. The home page offers:

• pdf-, ps- or dvi-files or arXiv-links of papers, books, theses, slides of talks and lecture notes in valuation theory
• information about upcoming conferences and events (below) and past conferences and events,
• a page for open problems and, hopefully, their solutions.

If you have suggestions, questions, ideas, news, or if you want your name and address on the above mentioned list, or if you have a recent paper in or applying valuation theory, then write to

Have a look at:

• commalg.org (Commutative Algebra Server)
• The Topology Atlas
• The Number Theory Web
• MODNET
