报告题目：Dilations of oblique dual pairs of Hilbert-Schmidt frame sequences
报告摘要：In this talk, we will discuss the dilation problem on oblique dual pairs of Hilbert-Schmidt frame (HS-frame) sequences in Hilbert spaces. Firstly, we present a characterization for all oblique duals of a given HS-frame sequence. Then it is shown that any oblique dual pair (Type I dual pair) of HS-frame sequences in a Hilbert space can be dilated to an oblique dual pair (Type I dual pair) of HS-Riesz sequences in a larger Hilbert space, and we obtain a characterization for an HS-frame sequence to have a Parseval Type II dual by orthogonal dilation. Finally, a condition under which an oblique dual pair of HS-frame sequences in a Hilbert space can be obliquely dilated to a dual pair of HS-Riesz bases for the same space is given.

报告题目：Fock projection on weighted 
spaces
报告摘要：Projections are essential building blocks of operator theory on spaces of
analytic functions. One cornerstone is to characterize their boundedness and compactness. In this talk, we will discuss the boundedness and compactness of Fock projection from 
to 
，where
and
are the Gaussian probability measures on 
.Some applications on Berezin transform and generalized Fock projection are also discussed.

报告题目：Complex Symmetry of Operators on Fock-Sobolev Spaces
报告摘要：An operator T∈BH is complex symmetric if there exists a conjugation C on H such that CTC=T*. In this talk, we mainly discuss when a weighted composition operator Wφ,ψ or a Toeplitz operator Tφ on the Fock-Sobolev space F2,m, is complex symmetric with respect to certain conjugation Cλ.

报告题目：The polydisc version of Arveson's conjecture
报告摘要：In this talk, I will disscuss the essential normality of the quotient modules over the polydisc. The relationship between the essential normality and the distinguished variety will be considered. The talk is based on a series joint work with Prof Kunyu Guo(Fudan University) and Chong Zhao( Shandong University).

报告题目：Local properties of some Banach algebras
报告摘要：In this talk, we introduce some properties of local deivations, local automorphisns and local isometries. For a class of algebras, we pove that these local properties imply whole properties.
