Disc-presheaves and normal invariants
Oliver H. Wang
In this note, we elaborate on a result of Krannich--Kupers--Mehzer on Disc-presheaves. We show that equivalences of -truncated Disc-presheaves of manifolds yields homotopy equiv…
Smooth Models of Fibered Partially Hyperbolic Systems
Jonathan DeWitt, Meg Doucette, Oliver Wang
We study fibered partially hyperbolic diffeomorphisms. We show that as long as certain topological obstructions vanish and as long as homological minimum expansion dominates the di…
The Rational Homotopy of Stable -Smoothings
Oliver H. Wang
Smooth structures on high dimensional manifolds are classified by maps to the infinite loop space . The homotopy groups of this space are known to be finite. Given a compact…
The Whitehead group and stably trivial -smoothings
Oliver H. Wang
A closed manifold of dimension at least has only finitely many smooth structures. Moreover, smooth structures of are in bijection with smooth structures of $M\times\mat…
Chern class obstructions to smooth equivariant rigidity
Oliver H. Wang
By work of Kirby-Siebenmann \cite{KirbySiebenmann} and Kervaire-Milnor \cite{KervaireMilnor}, there are only finitely many smooth manifolds homeomorphic to a given closed topologic…
Torus bundles over lens spaces
Oliver H. Wang
Let be an odd prime and let be an action of on a lattice and let $Γ:=\mathbb{Z}^n\rtimes_ρ\mathbb{Z}/p…
A spectral sequence for Dehn fillings
Oliver H. Wang
We study how the cohomology of a type relatively hyperbolic group pair changes under Dehn fillings (i.e. quotients of group pairs). For sufficiently lo…
