STABLE CLASS OF EQUIVARIANT ALGEBRAIC VECTOR BUNDLES OVER REPRESENTATIONS [PDF]

Journal of the Korean Mathematical Society, 2002
Summary: Let \(G\) be a reductive algebraic group and let \(B,F\) be \(G\)-modules. We denote by \(\text{VEC}_G(B,F)\) the set of isomorphism classes in algebraic \(G\)-vector bundles over \(B\) with \(F\) as the fiber over the origin of \(B\). \textit{G.

Equivariant algebraic vector bundles over adjoint representations

Osaka Journal of Mathematics, 1995
In this article, the authors extend a result of \textit{F. Knop} which appeared in Invent. Math. 105, No. 1, 217-220 (1991; Zbl 0739.20019) for the case of semisimple groups. Given a reductive complex algebraic group \(G\), let \(F\) be an irreducible \(G\)-module, and denote by \({\mathfrak g}\) the Lie algebra of \(G\). Denote by VEC\(_G({\mathfrak g}

On the equivariant vector bundles on $\mathbb{CP}^1$

Let $H$ be a subgroup of ${\rm PGL}(2,\mathbb C)$ (respectively, ${\rm SL}(2,\mathbb C)$) such that the Zariski closure in ${\rm PGL}(2,\mathbb C)$ (respectively, ${\rm SL}(2,\mathbb C)$) of some compact subgroup of $H$ contains $H$. We classify the $H$--equivariant holomorphic vector bundles on $\mathbb{CP}^1$. This generalizes \cite{BM} where $H$ was

Equivariant vector bundles over the upper half plane

Illinois Journal of Mathematics, 2003
The author classifies all the Hermitian holomorphic vector bundles equipped with an equivariant \(\text{ SL}(2,\mathbb R)\) action over the hyperbolic plane. The study relies on the fact that the action of \(\text{ SL}(2,\mathbb R)\) on the space of sections of such a bundle commutes with the Chern connection.
