Property {A} and duality in linear programming
G. C. Bell, A. Nagórko
Property A is a form of weak amenability for groups and metric spaces introduced as an approach to the famous Novikov higher signature conjecture, one of the most important unsolve…
Coarse free products
Greg Bell, Austin Lawson
We define a notion of free product for coarse spaces that generalizes the corresponding notion of a free product for groups. We show that free products preserve coarse properties s…
The space of persistence diagrams fails to have Yu's property A
Greg Bell, Austin Lawson, C. Neil Pritchard +1
We define a simple obstruction to Yu's property A that we call -prisms. This structure allows for a straightforward proof that the space of persistence diagrams fails to have pr…
Coarse direct products and property {C}
G. Bell, A. Lawson
We show that coarse property C is preserved by finite coarse direct products. We also show that the coarse analog of Dydak's countable asymptotic dimension is equivalent to the coa…
A construction of Nöbeling manifolds of arbitrary weight
G. C. Bell, A. Nagórko
For each cardinal , each natural number and each simplicial complex we construct a space and a map such that the following conditions…
Detecting topological properties of Markov compacta with combinatorial properties of their diagrams
G. C. Bell, A. Nagórko
We develop a formalism that allows us to describe Markov compacta with finite sets of diagrams that are building blocks of the entire sequence. This encodes complex, continuous spa…
