Farrell-Jones Conjecture

Algebra

The Farrell-Jones conjecture, named after F. Thomas Farrell and Lowell E. Jones, states in mathematics that certain assembly maps relating a group's equivariant homology to the algebraic K-theory or L-theory of its group ring are isomorphisms. The conjecture is motivated by interest in the target of these assembly maps, since the algebraic K-theory and L-theory of a group ring are often difficult to compute directly.

Facts
Statement
The Farrell-Jones conjecture, named after F. Thomas Farrell and Lowell E. Jones, states that certain assembly maps are isomorphisms. 1
Proposed Year
1993 1
Year of the Farrell and Jones paper introducing the conjecture.
Progress Toward Resolution
The fibered Farrell-Jones conjecture is proven for several classes of groups, including virtually cyclic, hyperbolic, CAT(0), solvable and mapping class groups; the general conjecture remains open. 1
