@article{Doan2019ACT, title={A Counter-Example to the Equivariance Structure on Semi-universal Deformation}, author={An Khuong Doan}, journal={The Journal of Geometric Analysis}, year={2019}, pages={1-15} }

If X is a projective variety and G is an algebraic group acting algebraically on X , we provide a counter-example to the existence of a G -equivariant extension on the formal semi-universal deformation of X .

The aim of this note is to explain in detail Remark 4.1 in [1]. Namely, by using the power series method, we prove that the action of the automorphism group G of the second Hirzebruch surface F2 on…

Semi-prorepresentability of formal moduli problems and equivariant structures

We generalize the notion of semi-universality in the classical deformation problems to the context of derived deformation theories. A criterion for a formal moduli problem to be semi-prorepresentable…

Classification of asymptotically conical Calabi-Yau manifolds

- Mathematics
- 2022

A Riemannian cone (C, gC) is by definition a warped product C = R + × L with metric gC = dr 2 ⊕ rgL, where (L, gL) is a compact Riemannian manifold without boundary. We say that C is a Calabi-Yau…

The Teichmüller and Riemann moduli stacks

The aim of this paper is to study the structure of the higher-dimensional Teichm\"uller and Riemann moduli spaces, viewed as stacks over the category of complex manifolds. We first show that the…

Group actions on local moduli space of holomorphic vector bundles

We prove that actions of complex reductive Lie groups on a holomorphic vector bundle over a complex compact manifold are locally extendable to its local moduli space.

Equivariant Kuranishi family of complex compact manifolds

We prove that actions of complex reductive Lie groups on a complex compact manifold is locally extendable to its Kuranishi family. This can be seen as an analogue of Rim's result (see [11]) in the…
