TILT: topological interface recovery in limited-angle tomography
Elli Karvonen, Matti Lassas, Pekka Pankka +1
A novel reconstruction method is introduced for the severely ill-posed inverse problem of limited-angle tomography. It is well known that, depending on the available measurement, a…

On the non-existence of certain branched covers
Pekka Pankka, Juan Souto
We prove that while there are maps $\bT^4\to\#^3(\bS^2\times\bS^2)$ of arbitrarily large degree, there is no branched cover from -torus to $\#^3(\bS^2\times \bS^2)$. More genera…

Quasiconformal extension fields
Pekka Pankka, Kai Rajala
We consider extensions of differential fields of mappings and obtain a lower energy bound for quasiconformal extension fields in terms of the topological degree. We also consider t…
