A Primer on Geometric Mechanics
Christian Lessig
Geometric mechanics is usually studied in applied mathematics and most introductory texts are hence aimed at a mathematically minded audience. The present note tries to provide the…
The Geometry of Radiative Transfer
Christian Lessig, Alex L. Castro
We present the geometry and symmetries of radiative transfer theory. Our geometrization exploits recent work in the literature that enables to obtain the Hamiltonian formulation of…
A Primer on Differential Forms
Christian Lessig
This primer is intended as an introduction to differential forms, a central object in modern mathematical physics, for scientists and engineers.
On the Mathematical Formulation of Radiance
Christian Lessig, Eugene Fiume, Mathieu Desbrun
Radiance is widely regarded as the principal quantity in light transport theory. Yet, the concept of radiance in use today has remained mostly unchanged since Lambert's work in the…
