Abstract Based on a special concept of the difference of sets, a new notion of the directional derivative of a set-valued map is presented. This theory is applied to set optimization problems with the ...

In this study, a new directional derivative is defied by using Minkowski difference. Some properties and existence theorems of this directional derivative are given. Moreover, necessary and sufficient ...

The problems, identified by the state for Purple Line Transit Partners, include multiple issues with concrete in the new Bethesda Metro entrance shaft, which will connect Wisconsin Avenue to the ...
