SKK groups of manifolds and non-unitary invertible TQFTs

Renee S. Hoekzema, Luuk Stehouwer, Simona Veselá

This work considers the computation of controllable cut-and-paste groups of manifolds with tangential structure . To this end, we apply the work o…

Nested cobordisms, Cyl-objects and Temperley-Lieb algebras

Maxine E. Calle, Renee S. Hoekzema, Laura Murray +3

We introduce a discrete cobordism category for nested manifolds and nested cobordisms between them. A variation of stratified Morse theory applies in this case, and yields generato…

A K-theory spectrum for cobordism cut and paste groups

Renee S. Hoekzema, Carmen Rovi, Julia Semikina

Cobordism groups and cut-and-paste groups of manifolds arise from imposing two different relations on the monoid of manifolds under disjoint union. By imposing both relations simul…

Orientability of high-dimensional manifolds with odd Euler characteristic

Renee S. Hoekzema

We call a manifold -orientable if the Stiefel-Whitney class vanishes for all (), generalising the notions of orientable (1-orientable) and spin (2-ori…

Cut and paste invariants of manifolds via algebraic K-theory

Renee S. Hoekzema, Mona Merling, Laura Murray +2

Recent work of Jonathan Campbell and Inna Zakharevich has focused on building machinery for studying scissors congruence problems via algebraic -theory, and applying these tools…

Manifolds with odd Euler characteristic and higher orientability

Renee S. Hoekzema

It is well-known that odd-dimensional manifolds have Euler characteristic zero. Furthemore orientable manifolds have an even Euler characteristic unless the dimension is a multiple…
