A Cartesian Bicategory of Polynomial Functors in Homotopy Type Theory

Eric Finster, Samuel Mimram, Maxime Lucas +1

Polynomial functors are a categorical generalization of the usual notion of polynomial, which has found many applications in higher categories and type theory: those are generated…

Exceptional scalar theories in de Sitter space

James Bonifacio, Kurt Hinterbichler, Austin Joyce +1

The special galileon and Dirac-Born-Infeld (DBI) theories are effective field theories of a single scalar field that have many interesting properties in flat space. These theories…

Vector-valued Spline Method for the Spherical Multiple-shell Electro-magnetoencephalography Problem

Sarah Leweke, Olaf Hauk, Volker Michel

Human brain activity is based on electrochemical processes, which can only be measured invasively. Therefore, quantities such as magnetic flux density (MEG) or electric potential d…
