Topological realizations of absolute Galois groups
... for all i ≥ 0, which are compatible with the isomorphisms in degrees i = 0, 1 for XF ? For algebraically closed fields F , the space XFM would have to be constructed in such a way as to freely adjoin the Steinberg relation on its cohomology groups; the general case should reduce to this case by desc ...

Matrix Groups
... complex numbers. We use these groups to motivate the definitions of groups, rings and fields, and to illustrate their properties. It is natural to generalize these matrix groups to general fields. In order to study these classical groups over arbitrary fields we discuss the theory of vector spaces o ...

Chern Character, Loop Spaces and Derived Algebraic Geometry
... equivalently a continuous map , where is the 1-category of finite dimensional complex vector spaces. Such an interpretation of vector bundles can be made rigorous if is considered as a topological stack. It is natural to expect that tmf is related in one way or another to -categories, and that cl ...
