Homology of GLn over algebraically closed fields

In this paper we define higher pre-Bloch groups
n(F) of a field F. When the base field is algebraically closed, we study its connection to the homology of the general linear groups with coefficients in
/l
, where l is a positive integer. As a result of our investigation we give a necessary and sufficient condition for the natural map Hn(GLn–1(F),
/l
)
Hn(GLn(F),
/l
) to be bijective. We prove that this map is bijective for n
4. We also demonstrate that a certain property of
n(
) is equivalent to the validity of the Friedlander–Milnor isomorphism conjecture for (n+1)th homology of GLn(
).
