A GIT construction of moduli spaces of sheaves of length 2

Yikun Qiao

Let $k$ be an algebraically closed field of characteristic zero. Let $Sch / k$ denote the category of schemes of finite type over $k$ . Let $B$ be a connected pro…

GIT for $U^$ -actions on algebraic $C$ -schemes

Yikun Qiao

We extend the $U^$ -theorem for projective varieties proved in arXiv:1601.00340 and arXiv:1607.04181 to projective schemes over $C$ . The condition "ss=s" required in arX…

Commutativity of normal compact operator via projective spectrum

Tong Mao, Yikun Qiao, Penghui Wang

In this note we obtain commutativity criteria for normal compact operators using the projective spectrum. We thus improve a corresponding result obtained by Chagouel, Stessin and Z…
