Smooth Polar B-Splines with High-Order Regularity at the Origin
Peiyou Jiang, Roman Hatzky, Zhixin Lu +5
We introduce a smooth B-spline discretization in polar coordinates on the unit disc that corrects the loss of regularity present at the origin caused by the coordinate singularity…

The Linearized Vlasov-Maxwell System as a Hamiltonian System
Dominik Bell, Martin Campos Pinto, Stefan Possanner +1
We present a Hamiltonian formulation for the linearized Vlasov-Maxwell system with a Maxwellian background distribution function. We discuss the geometric properties of the model a…
