New Exact and Numerical Solutions of the (Convection-)Diffusion Kernels on SE(3) [PDF]

, 2016
We consider hypo-elliptic diffusion and convection-diffusion on $\mathbb{R}^3 \rtimes S^2$, the quotient of the Lie group of rigid body motions SE(3) in which group elements are equivalent if they are equal up to a rotation around the reference axis.
