Equivariant map superalgebras [PDF]
Mathematische Zeitschrift, 2015 Suppose a group $\Gamma$ acts on a scheme $X$ and a Lie superalgebra $\mathfrak{g}$. The corresponding equivariant map superalgebra is the Lie superalgebra of equivariant regular maps from $X$ to $\mathfrak{g}$.

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)

Equivariant Phantom maps [PDF]
arXiv, 2001 A successful generalization of phantom map theory to the equivariant case for all compact Lie groups is obtained in this paper. One of the key observations is the discovery of the fact that homotopy fiber of equivariant completion splits as product of equivariant Eilenberg-Maclane spaces which seems impossible at first sight by the example of ...

The degree of equivariant maps
Topology and its Applications, 2004 AbstractIn this paper, we study the degree of equivariant maps between G-manifolds by using cohomological index theory. As applications, we have some Borsuk–Ulam type theorems for Stiefel manifolds.

Reidemeister numbers of equivariant maps
Topology and its Applications, 1995 AbstractIn this paper, we generalize the arithmetic congruence relations among the Reidemeister numbers of iterates of maps to similar congruences for equivariant maps.

On classification of global dynamics for energy-critical equivariant harmonic map heat flows and radial nonlinear heat equation [PDF]
Communications on Pure and Applied Mathematics, EarlyView.Abstract We consider the global dynamics of finite energy solutions to energy‐critical equivariant harmonic map heat flow (HMHF) and radial nonlinear heat equation (NLH). It is known that any finite energy equivariant solutions to (HMHF) decompose into finitely many harmonic maps (bubbles) separated by scales and a body map, as approaching to the ...

Equivariant prequantization and the moment map
Forum Mathematicum, 2020 Abstract If ω is a closed G-invariant 2-form and μ is a moment map, we obtain necessary and sufficient conditions for equivariant prequantizability that can be computed in terms of the moment map μ. Our main result is that G-equivariant prequantizability is related to the fact that the moment map μ should be quantized for certain vectors
