Gowers-Maurey's space and its conjugate space被引量:5
《Chinese Science Bulletin》1997年第1期14-17,共4页ZHONG HuaijieDepartment of Mathematics, Fujian Normal University, Fuzhou 350007, China 
RECENTLY Gowers and Maurey constructed the first example of Banach space containing no unconditional basic sequence. We denote this space by X_G, in this note. Using the results in ref. [1], some further studies and r...

Construction of indecomposable definite Hermitian forms
《Chinese Science Bulletin》1995年第3期177-181,共5页朱福祖 
Let F=Q(-m1/2) (m>0 and square-free) be an imaginary quadratic field and Dm the ring of algebraic integers in F. The field F has a unique non-trivial involution (the complex conjugation) w...

THE DIFFERENTIAL REALIZATION OF NEW SOLUTIONS FOR YANG-BAXTER EQUATION
《Chinese Science Bulletin》1992年第5期379-382,共4页孙昌璞 
project supported by the national natural science foundation for young scientice wourkes of china
I. INTRODUCTION Yang-Baxter equation plays a crucial role in the nonlinear integrable system. Its standard solutions can be constructed in terms of the universal R-matrix and representations of the corresponding quant...

DIMENSIONS OF THE PROJECTIVE INDECOMPOS ABLE MODULES OVER CLASSICAL 0-HECKE ALGEBRAS
《Chinese Science Bulletin》1992年第3期177-180,共4页陈承东 
Project supported by the National Natural Science Foundation of China.
Let W be a classical Weyl group and ∏ be the corresponding system of simple roots. For w∈ W, let R(w)={α∈∏|l(ws_α)<l(w)}, where we denote by s_α the simple reflection in the hyperplane orthogonal to α for ...

THE RELATION BETWEEN THE BORDISM CLASS OF MANIFOLDS WITH INVOLUTION AND THE BORDISM CLASS OF ITS FIXED POINT SET
《Chinese Science Bulletin》1989年第16期1327-1330,共4页吴振德 刘宗泽 
In [1], C. Kosniowshi and R. E. Stong have pointed out that the bordism class of fixed point set can determine nothing about manifold with involution. In this note, we are to consider the case of (M2n-k, T)...
