Perceptual Learning, Long-Range Horizontal Connections And Top-Down Influences In Primary Visual Cortex
Valentin Piëch
Jan 01, 0001
The earliest cortical stage of visual processing, the primary visual cortex, has long been seen as a static preprocessor that finds local edges and their orientation like a linear filter bank, and passes this information on to...

We study a simplified model for the micromagnetic energy functional in a specific asymptotic regime. The analysis includes a construction of domain walls with an internal zigzag pattern and a lower bound for the energy of a...

Dec 05, 2022

We analyse two variants of a nonconvex variational model from micromagnetics with a nonlocal energy functional, depending on a small parameter ϵ>0. The model gives rise to transition layers, called Néel walls, and we study...

Jul 01, 2016
We study a variational model from micromagnetics involving a nonlocal Ginzburg-Landau type energy for S1-valued vector fields. These vector fields form domain walls, called Néel walls, that correspond to...

Nov 05, 2017
We study a nonlocal Allen-Cahn type problem for vector fields of unit length, arising from a model for domain walls (called Néel walls) in ferromagnetism. We show that the nonlocal term gives rise to new features in the energy...
