Algebraic and combinatorial codimension-1 transversality
Andrew Ranicki
The Waldhausen construction of Mayer-Vietoris splittings of chain complexes over an injective generalized free product of group rings is extended to a combinatorial construction of…
Generalized Arf invariants in algebraic L-theory
Markus Banagl, Andrew Ranicki
The difference between the quadratic L-groups L_*(A) and the symmetric L-groups L^*(A) of a ring with involution A is detected by generalized Arf invariants. The special case A=Z[x…
On the calculation of UNil
Frank Connolly, Andrew Ranicki
Cappell's codimension 1 splitting obstruction surgery group UNil_n(R;R,R) of a ring with involution R is a direct summand of the Wall surgery obstruction group L_n(R[D_{\infty}]) o…
Noncommutative localization in topology
Andrew Ranicki
A survey of the applications of the noncommutative Cohn localization of rings to the topology of manifolds with infinite fundamental group, with particular emphasis on the algebrai…
Circle valued Morse theory and Novikov homology
Andrew Ranicki
An introduction to circle valued Morse theory and Novikov homology, from an algebraic point of view.
The structure set of an arbitrary space, the algebraic surgery exact sequence and the total surgery obstruction
Andrew Ranicki
An introduction to the applications of algebraic surgery to the structure theory of high-dimensional topological manifolds.
