| Abstract: |
| I will report on joint work with Tamme. In the first part of the talk, I will recall an earlier theorem of Tamme and mine about (the failure of) excision in K-theory, and some of its applications. The main motivation of our new work was to find an explicit formula for a ring spectrum (the circle-dot ring) which appears in this earlier work. Our new theorem says that this circle-dot ring is often a pushout of associative algebras. I will present an example related to the calculation of the K-theory of dual numbers and coordinate axes over rational rings, and explain the relationship of our results with results of Waldhausen on pure extensions. |
