— Lee et al. recently published the paper “Vector field microscopic imaging of light” showing intriguing maps of vectors on the nanoscale 1. It claims the first experimental mapping of vector fields ...
Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations ...
This is a preview. Log in through your library . Abstract This paper deals with variational principles on thin films subject to linear PDE constraints represented by a constant-rank operator 𝒜. We ...
In this paper, we introduce the notion of Jacobi-type vector fields on Riemannian manifolds, which is a generalization of the Jacobi field along a geodesic. We study Ricci solitons with positive Ricci ...
