Equivariant extensions of maps [PDF]
Pacific Journal of Mathematics, 1973 This paper treats extension and retraction properties in the category *$/9 of compact metric spaces with periodic maps of a prime period p; the subspaces and maps in J^p are called equivariant subspaces and maps, respectively. The motivation of the paper is the following question: Let E be a Euclidean space and α: E X E-> E X E be the involution (x, y)

Publications of the Research Institute for Mathematical Sciences, 1988 This paper contains a study of the characterization of the equivariant phantom maps by means of the equivariant localization and the equivariant completion. The equivariant integral approximation and the equivariant Miller-Zabrodsky theorem will be used to describe the homotopy set of the equivariant phantom maps by the equivariant cohomology groups.

Rotation Equivariant Convolutional Neural Networks for Hyperspectral Image Classification
IEEE 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.
