    Towards non-reductive geometric invariant theory by Doran, B, Kirwan, F

    Published 2007
    “…A guiding goal for us is to understand the cohomology of "quotients" under such actions, by generalizing (from reductive to non-reductive group actions) existing methods involving Mumford's geometric invariant theory (GIT). We concentrate on actions of unipotent groups H, and define sets of stable points X s and semistable points X ss, often explicitly computable via the methods of reductive GIT, which reduce to the standard definitions due to Mumford in the case of reductive actions. …”

    Invariant theory and scaling algorithms for maximum likelihood estimation by Améndola, C, Kohn, K, Reichenbach, P, Seigal, AL

    Universal structures in C-linear enumerative invariant theories by Gross, J, Joyce, D, Tanaka, Y

    Published 2022
    “…An enumerative invariant theory in algebraic geometry, differential geometry, or representation theory, is the study of invariants which `count' τ-(semi)stable objects E with fixed topological invariants [[E]]=α in some geometric problem, by means of a virtual class [Mssα(τ)]virt in some homology theory for the moduli spaces Mstα(τ)⊆Mssα(τ) of τ-(semi)stable objects. …”
