    On enhanced general linear groups: nilpotent orbits and support variety for Weyl module by Yunpeng Xue

    Published 2023-04-01
    “…Associated with a reductive algebraic group $ G $ and its rational representation $ (\rho, M) $ over an algebraically closed filed $ {\bf{k}} $, the authors define the enhanced reductive algebraic group $ {\underline{G}}: = G\ltimes_\rho M $, which is a product variety $ G\times M $ and endowed with an enhanced cross product in <sup>[<xref ref-type="bibr" rid="b5">5</xref>]</sup>. …”

    Stratifying quotient stacks and moduli stacks by Berczi, G, Hoskins, V, Kirwan, F

    Published 2018
    “…Recent results in geometric invariant theory (GIT) for non-reductive linear algebraic group actions allow us to stratify quotient stacks of the form [X∕H], where X is a projective scheme and H is a linear algebraic group with internally graded unipotent radical acting linearly on X, in such a way that each stratum [S∕H] has a geometric quotient S∕H. …”

    Torus Actions on Quotients of Affine Spaces by Ana-Maria Brecan, Hans Franzen

    Published 2023-08-01
    “…We study the locus of fixed points of a torus action on a GIT quotient of a complex vector space by a reductive complex algebraic group which acts linearly. We show that, under the assumption that $G$ acts freely on the stable locus, the components of the fixed point locus are again GIT quotients of linear subspaces by Levi subgroups.…”
