- Which homology classes really come from stable maps of spheres?
- Counting the chromatic layers lost when taking fixed points
- A finite chain of building rules for local stable homotopy
- Local finiteness does not guarantee a finite global construction
- A model of spaces inside every strict higher category dimension
- The same homotopy type can hide different aspherical four-manifolds
- Chromatic splitting: the pieces can fit without splitting apart
- A finite complex whose third dimension cannot be removed
