  • [外文期刊] Du, W.S. Hu, B.Q. Zhao, Y. 《Information Sciences: An International Journal》, ISTIC EI SCI PKU CSSCI 2013
    The connections between special types of fuzzy relations and properties of fuzzy rough approximation operators have been established in recent years, but ?-Euclidean fuzzy relation has not been conside...

  • [外文期刊] Dan Meng Xiaohong Zhang Keyun Qin 《Computers & Mathematics with Applications: An International Journal》, ISTIC EI SCI PKU CSSCI 2011 12
    Fuzzy set theory, soft set theory and rough set theory are mathematical tools for dealing with uncertainties and are closely related. Feng et al. introduced the notions of rough soft set, soft rough se...

  • [外文期刊] Murat Diker 《Fundamenta Informaticae》, ISTIC EI SCI PKU CSSCI 2011 3/4
    In this paper, we consider the Alexandroff topology for texture spaces. We prove that there exists a one-to-one correspondence between the Alexandroff ditopologies, and the reflexive and transitive dir...

  • [外文期刊] Diker, M 《Information Sciences: An International Journal》, ISTIC EI SCI PKU CSSCI 2010 8
    This paper presents a discussion on rough set theory from the textural point of view. A texturing is a family of subsets of a given universal set U satisfying certain conditions which are generally bas...
