Calculus of Generalized quasi-differentiable Functions I: Some Results on the Space of Pairs of Convex-Set Collections
收藏 引用
Northeastern Mathematical Journal 2003年 第1期19卷 75-85页
作者: 张宏伟 张立卫 夏尊铨 Department of Mathematics Dalian University of TechnologyDalian116024
A Riesz space K1 whose elements are pairs of convex-set collections is presented for the study on the calculus of generalized quasi-differentiable functions. The space K1 is constructed by introducing a well-defined e... 详细信息

Advances in Pure Mathematics 2013年 第4期3卷 415-429页
作者: Sobhy El-Sayed Ibrahim Department of Mathematics Faculty of Science Benha University Benha Egypt
In this paper, we consider the general quasi-differential expressions each of order n with complex coefficients and their formal adjoints on the interval (a,b). It is shown in direct sum spaces of functions defined on... 详细信息
