Papers
Vanishing Pohozaev constant and removability of singularities
TL;DR: In this article, the authors introduced a new quantity called the Pohozaev constant, which measures the extent to which the Poohaev identity fails and provides a characterization of the singular behavior of a solution at an isolated singularity.
Symmetries and conservation laws of a nonlinear sigma model with gravitino
TL;DR: In this paper, the authors studied the symmetries and invariances of a version of the action functional of the nonlinear sigma model with gravitino, which is invariant under rescaled conformal transformations, super Weyl transformations, and diffeomorphisms.
A simple parameter can switch between different weak-noise–induced phenomena in a simple neuron model
TL;DR: It is shown that at least two weak-noise–induced resonance phenomena, SISR and inverse stochastic resonance (ISR), can be related by a simple parameter switch in one of the simplest models, the FitzHugh-Nagumo (FHN) neuron model.
The qualitative behavior at the free boundary for approximate harmonic maps from surfaces.
TL;DR: In this article, the energy identity and the no neck property hold for the harmonic map heat flow with free boundary at finite singular time as well as at infinity time, assuming that the tension field of the map is constant.
A maximum principle for generalizations of harmonic maps in Hermitian, affine, Weyl, and Finsler geometry
TL;DR: In this article, the maximum principle of Jager-Kaul for harmonic maps holds for a more general class of maps, $$V$$ -harmonic maps, including Hermitian harmonic maps, affine harmonic maps and Finsler maps.
