WebIn mathematics, geometric invariant theory (or GIT) is a method for constructing quotients by group actions in algebraic geometry, used to construct moduli spaces.It was developed by David Mumford in 1965, using ideas from the paper (Hilbert 1893) in classical invariant theory.. Geometric invariant theory studies an action of a group G on an algebraic variety … WebMay 3, 2024 · Extending results of Rais–Tauvel, Macedo–Savage, and Arakawa–Premet, we prove that under mild restrictions on the Lie algebra \mathfrak {q} having the polynomial ring of symmetric invariants, the m -th Takiff algebra of \mathfrak {q} , \mathfrak {q} m , also has a polynomial ring of symmetric invariants.
