Hyperbolic Equivariants of Rational Maps [PDF]

open access: yesInternational Mathematics Research Notices, 2021
AbstractLet $K$ denote either ${\mathbb{R}}$ or ${\mathbb{C}}$. In this article, we study two new equivariants and a new invariant attached to a rational map $f\in K(z)$ under the action of conjugation by ${\operatorname{SL}}_2(K)$. The 1st two equivariants naturally live on real hyperbolic $[K:{\mathbb{Q}}]+1$ space and carry information about the ...

Rotation Equivariant Convolutional Neural Networks for Hyperspectral Image Classification

open access: yesIEEE Access, 2020
Detection of surface material based on hyperspectral imaging (HSI) analysis is an important and challenging task in remote sensing. It is widely known that spectral-spatial data exploitation performs better than traditional spectral pixel-wise procedures.

Equivariant embedding theorems and topological index maps [PDF]

open access: yes, 2009
The construction of topological index maps for equivariant families of Dirac operators requires factoring a general smooth map through maps of a very simple type: zero sections of vector bundles, open embeddings, and vector bundle projections.

RiDOP: A Rotation-Invariant Detector with Simple Oriented Proposals in Remote Sensing Images

open access: yesRemote Sensing, 2023
Compared with general object detection with horizontal bounding boxes in natural images, oriented object detection in remote sensing images is an active and challenging research topic as objects are usually displayed in arbitrary orientations.

On equivariant deformation of maps [PDF]

open access: yesPublicacions Matemàtiques, 1988
We work in the smooth category: manifolds and maps are meant to be smooth. Let G be a finite group acting on a connected closed manifold X and f an equivariant self-map on X with flA fixpointfree, where A is a closed invariant submanifold of X with codim A >- 3. The purpose of this paper is to give a proof using obstruction theory of the following fact:

Existence of Equivariant Biharmonic Maps [PDF]

open access: yesInternational Mathematics Research Notices, 2015
We consider two compact Riemannian manifolds M and N and a compact Lie group G that acts on both by isometries. Under certain assumptions on the structure of M and of the quotient space M/G, we construct equivariant biharmonic maps u: M → N with prescribed boundary data.

Local Weyl modules for equivariant map algebras with free abelian group actions [PDF]

open access: yes, 2011
Suppose a finite group acts on a scheme X and a finite-dimensional Lie algebra g. The associated equivariant map algebra is the Lie algebra of equivariant regular maps from X to g.
