A Cortical-Inspired Contour Completion Model Based on Contour Orientation and Thickness

Journal of Imaging
An extended four-dimensional version of the traditional Petitot–Citti–Sarti model on contour completion in the visual cortex is examined. The neural configuration space is considered as the group of similarity transformations, denoted as M=SIM(2).

Totally geodesic subvarieties in the moduli space of Riemann surfaces

, 2016
We will present an algebraic surface in the moduli space of triply punctured tori with the remarkable property that it is totally geodesic for Teichmuller metric. Our example reveals a surprising connection between Teichmuller theory and the geometry of

Nonlinear excitation of energetic particle driven geodesic acoustic mode by resonance overlap with Alfvén instability in ASDEX Upgrade

Scientific Reports
The Alfvén instability nonlinearly excited the energetic-particle-driven geodesic acoustic mode on the ASDEX-Upgrade tokamak, as demonstrated experimentally.

Recognizing Weighted Means in Geodesic Spaces

Foundations of Computational Mathematics
Geodesic metric spaces support a variety of averaging constructions for given finite sets. Computing such averages has generated extensive interest in diverse disciplines. Here we consider the inverse problem of recognizing computationally whether or not a given point is such an average, exactly or approximately. In nonpositively curved spaces, several

Totally geodesic submanifolds of Teichmuller space [PDF]

We show that any totally geodesic submanifold of Teichmuller space of dimension greater than one covers a totally geodesic subvariety, and only finitely many totally geodesic subvarieties of dimension greater than one exist in each moduli space.This is a
