UNBOUNDED COMPLEX SYMMETRIC TOEPLITZ OPERATORS

In this paper,we study unbounded complex symmetric Toeplitz operators on the Hardy space H²(D) and the Fock space g².The technique used to investigate the complex symmetry of unbounded Toeplitz operators is different from that used to investigate the complex symmetry of bounded Toeplitz operators.

加权Dirichlet空间Dφ^2上的复合算子

设D是复平面中单位圆盘，φ：D→R是一个次调和函数，Dφ^2是D上的加权Dirichlet空间．对某类次调和函数φ文章研究了Dφ^2上的复合算子Cφ，分别得到了Cφ为Dφ^2上的有界、紧、Schatten p-类算子的特征．     

Hardy空间上复合算子的伴随表示

Hardy空间上的复合算子的伴随算子具有很好的性质,但对一般情形而言,一直没有关于它的明确表达式．Cowen于1988年给出了(?)为D上的线性分式自映射情形时C*(?)的表达式,并且于2000年给出了n个变量情形的推广．他指出,正是由于没有一般情形的C*(?)的表达式,在很大程度上,阻碍了复合算子理论的发展．该文给出了Hardy空间上的复合算子伴随的准确表达式．     

Weighted composition operators on the Hilbert space of Dirichlet series

In this paper, we study weighted composition operators on the Hilbert space of Dirichlet series with square summable coefficients. The Hermitianness, Fredholmness and invertibility of such operators are characterized, and the spectra of compact and invertible weighted composition operators are also described.     

序锥度量空间中涉及距离改变函数的拟压缩的公共不动点结果（英文）

Some common fixed point results for mappings satisfying a quasi-contractive condition which involves altering distance functions are obtained in partially ordered complete cone metric spaces. A sufficient condition for the uniqueness of common fixed point is proved. Also, an example is given to support our results.     

Hlder不等式和Minkowski不等式的推广

本文利用变分方法对多个变元的不含变元导数的Holder不等式和Minkowski不等式进行了推广．此种方法的主要意义不在于证明传统的不等式，而在于发现新的不等式．
