On Rough Intuitionistic Fuzzy Ideals（Filters） in Lattices
《Chinese Quarterly Journal of Mathematics》2014年第3期381-391,共11页HE Peng-fei YANG Yong-wei XIN Xiao-long 
Supported by the Graduate Independent Innovation Foundation of Northwest University(YZZ12061);Supported by the Scientific Research Program Funded by Shaanxi Provincial Education Department(2013JK0562)
In this paper, we introduce a new algebraic structure, called a rough intuitionistic fuzzy ideal(filter) which is a generalized intuitionistic fuzzy ideal(filter) of a lattice and study some related properties of such...

The Spectrum of Positive Operators on Hilbert Lattices
《Chinese Quarterly Journal of Mathematics》2007年第1期52-56,共5页DENG Chun-yuan DU Hong-ke 
Supported by the National Natural Science Foundation of China(19771056,10571113)
Some spectral characterizations of positive operators on Hilbert lattices are presented. The application of these results can yield some equivalent relations of an irreducible positive operator. Some related results f...

The Classification of Positive Definite Unimodular Lattices Over Z[(1+21^(1/2))/2]
《Chinese Quarterly Journal of Mathematics》2000年第2期87-93,共7页王瑞卿 
In this paper, the author applies adjacent lattice method and Siegel mass formula to determine the classes of positive definite unimodular lattices of rank 4 over Z , and obtains that the class number of unit genus ...

Note on Reflexive Algebras with Non-distribut iveInvariant Lattices
《Chinese Quarterly Journal of Mathematics》1998年第4期59-63, ,共5页赵君喜 
In this note,we discuss some properties of reflexive algebras on a Hilbert space with invariant subspace lattices as realizations of the pentagon and the double triangle and give some results concerning hyperreflexivi...

Atoms of Lattices of Supernilpotent and Special Radicals
《Chinese Quarterly Journal of Mathematics》1996年第4期44-49, ,共6页钟德强 
In this paper we define pure-supernilpotent radical and show that the class of all pureaupernilpotent radicals forms a complete lattice. We discuss some open questions on lattices of supernilpotent and special radica...
