Geometric invariant theory
WebThe Geometric Invariant Theory quotient is a construction that partitions G-orbits to some extent, while preserving some desirable geometric properties and structure. For a ne sets, the construction of the GIT quotient is well understood and is determined uniquely. In the projective case, the natural way to construct a quotient WebGeometric invariant theory is about constructing and studying the properties of certain kinds of quotients; a good example would be the moduli space of semi-stable vector bundles on an algebraic variety. In my mind, the difference is this: Classical invariant theory is a collection of results about the interaction between group actions and ...
