Semisimple Hopf Algebras via Geometric Invariant Theory [PDF]
We study Hopf algebras via tools from geometric invariant theory. We show that all the invariants we get can be constructed using the integrals of the Hopf algebra and its dual together with the multiplication and the comultiplication, and that these ...

Geometric invariant theory and flips [PDF]
We study the dependence of geometric invariant theory quotients on the choice of a linearization. We show that, in good cases, two such quotients are related by a flip in the sense of Mori, and explain the relationship with the minimal model programme ...

Variation of geometric invariant theory quotients [PDF]
Geometric Invariant Theory gives a method for constructing quotients for group actions on algebraic varieties which in many cases appear as moduli spaces parameterizing isomorphism classes of geometric objects (vector bundles, polarized varieties, etc.).

Instantons and geometric invariant theory [PDF]
By the theorem of Atiyah-Ward (anti-)self-dual Yang-Mills potentials on \(S^ 4\) correspond to certain holomorphic vector bundles on \({\mathbb{P}}_ 3({\mathbb{C}})\) via the twistor fibering \({\mathbb{P}}_ 3({\mathbb{C}})\to S^ 4\). In this paper a new correspondence is established by considering instead holomorphic vector bundles on \({\mathbb{P}}_ ...

Moment maps and geometric invariant theory [PDF]
These lectures centered around the Kempf-Ness theorem, which describes the equivalence between notions of quotient in symplectic and algebraic geometry.

Equivariant Dirac operators and differentiable geometric invariant theory [PDF]
In this paper, we give a geometric expression for the multiplicities of the equivariant index of a spin-c Dirac operator.

Relative Geometric Invariant Theory and Universal Moduli Spaces [PDF]
We expose in detail the principle that the relative geometric invariant theory of equivariant morphisms is related to the GIT for linearizations near the boundary of the G-effective ample cone.

Geometric invariant theory and projective toric varieties [PDF]
This is an expository paper in which we define projective GIT quotients and introduce toric varieties from this perspective. It is intended primarily for readers who are learning either invariant theory or toric geometry for the first time.Comment: 9 ...
