This paper presents a connection between qualitative matrix theory and linear complementarity problems (LCPs). An LCP is said to be sign-solvable if the set of the sign patterns of the solutions is uniquely determined by the sign patterns of the given coefficients. We provide a characterization for

โฆ Synopsis
In this paper, we introduce some new notions of (ฮฑ, ฮณ )-exceptional family of elements (in short, (ฮฑ, ฮณ )-(EFE)) and (ฮฑ, ฮฒ, ฮณ )-exceptional family of elements (in short, (ฮฑ, ฮฒ, ฮณ )-(EFE)) for a pair of continuous functions involved in the implicit complementarity problem (in short, ICP). Based upon these notions and the topological degree theory, we studied the feasibility and strictly feasibility of (ICP) in R n and an infinite-dimensional Hilbert space H , respectively. As special cases, we obtain the feasibility and strictly feasibility of complementarity problems and partly answered the second open problem (P2) proposed by Isac [G. Isac, Exceptional families of elements, feasibility and complementarity,

In this work, we introduce a new notion of an exceptional family of elements for a J -completely continuous field, and utilize this notion to study the solvability for a class of generalized f -complementarity problems in Banach spaces. Employing the Leray-Schauder alternative theorem and the genera
