Farkas-type theorems for interval linear systems
Mengxue Xia, Wei Li, Haohao Li · Linear and Multilinear Algebra · 2014
We describe some Farkas-type necessary and sufficient conditions for solvability and feasibility of interval linear equations and inequalities, in a unified form. For the convenient choice in practice of theory and calculations, some different but equivalent forms of the Farkas-type conditions for interval linear systems are also discussed.
