Abstract

We extend the row-sufficiency and column-sufficiency of a linear transformation from $${mathbb {R}^n}$$ to the setting of Euclidean Jordan algebras. For linear complementarity problems over symmetric cones, we show that the column-sufficiency along with Cross Commutative property is equivalent to the convexity of the solution set, while the row-sufficiency is necessary for the existence of solutions under some conditions.
