Topological Algebraic Geometry Workshop
Oslo, September 4th-8th, 2006

The Strategic University Program in Pure Mathematics (Suprema) at the Department of Mathematics, University of Oslo, invites to a Workshop on Derived Algebraic Geometry, from Monday September 4th to Friday September 8th, 2006. The lectures will take place in seminar room B 1036, on the 10th floor of the N. H. Abel building.

(Also known as the Derived Algebraic Geometry Workshop. "Topological", as suggested by Haynes Miller, is in line with "topological Hochschild (co-)homology" and "topological André-Quillen (co-)homology", indicating the use of the sphere spectrum as the base ring. Other names are "brave new algebraic geometry", "homotopical algebraic geometry" and "spectral algebraic geometry".)

This will be the conclusion of a Masterclass by Jacob Lurie, on Derived Algebraic Geometry and Elliptic Cohomology. The theme of the workshop will be more broadly defined, including the point of view on structured ring spectra as rings of functions on new geometries.
