Homogeneous spaces, algebraic $K$-theory and cohomological dimension of fields

نویسندگان

چکیده

Let $q$ be a non-negative integer. We prove that perfect field $K$ has cohomological dimension at most $q+1$ if, and only for any finite extension $L$ of homogeneous space $Z$ under smooth linear connected algebraic group over $L$, the $q$-th Milnor $K$-theory is spanned by images norms coming from extensions which rational point. also variant this result imperfect fields.

Algebraic K - Theory and Configuration Spaces

Its importance lies in the fact that the right hand side of the above equivalence (which wewill briefly refer to as a configuration space model) is a much smaller space than the function space on the left, and thus is much easier to deal with. The second author noted that in the configuration space model, one can replace the X" by spaces like BGln(R). For there is an obvious ~n action on BGln(R...

Derived Representation Theory and the Algebraic K-theory of Fields

Quillen’s higher algebraic K-theory for fields F has been the object of intense study since their introduction in 1972 [26]. The main direction of research has been the construction of “descent spectral sequences” whose E2-term involved the cohomology of the absolute Galois groupGF with coefficients in the algebraic K–theory of an algebraically closed. The form of such a spectral sequence was c...
