In 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 … See more Invariant theory is concerned with a group action of a group G on an algebraic variety (or a scheme) X. Classical invariant theory addresses the situation when X = V is a vector space and G is either a finite group, or one of the See more • GIT quotient • Geometric complexity theory • Geometric quotient • Categorical quotient • Quantization commutes with reduction See more Geometric invariant theory was founded and developed by Mumford in a monograph, first published in 1965, that applied ideas of nineteenth century invariant theory, … See more If a reductive group G acts linearly on a vector space V, then a non-zero point of V is called • unstable if 0 is in the closure of its orbit, • semi-stable if 0 is … See more WebDec 17, 2005 · These notes give an introduction to Geometric Invariant Theory and symplectic reduction, with lots of pictures and simple examples.
