Surgery transfer. (English) Zbl 0677.57012

Algebraic topology and transformation groups, Proc. Conf., Göttingen/FRG 1987, Lect. Notes Math. 1361, 167-246 (1988).
From the introduction of the paper: Given a Hurewicz fibration \(F\to E\xrightarrow{p}B\) with fibre an \(n\)-dimensional Poincaré complex \(F\) we construct algebraic transfer maps in the Wall surgery obstruction groups \[ p^ *: L_m(\mathbb{Z}[\pi_1(B)])\to L_{m+n}(\mathbb{Z}[\pi_1(E)])\quad (m\geq 0) \] and prove that they agree with the geometrically defined transfer maps. The construction of the quadratic \(L\)-theory transfer maps is by a combination of the algebraic surgery theory of Ranicki and the method used by Lück to define the algebraic \(K\)-theory transfer maps for a fibration with finitely dominated fibre \(F\). The authors promise computations of the composition of \(p^*\) with \(p_*\) (the change of rings map) on either side, as well as some vanishing results in future work.
