\begin{abstract}
In matrix theory, various algebraic, fixed point, and degree theory methods have been used to study the solvability of equations of the form $f(X) = Q$, where $f$ is a transformation (possibly nonlinear), $Q$ is a semidefinite/definite matrix and $X$ varies over the cone of
semidefinite matrices. In this talk, we describe a new method based on complementarity ideas. This method gives a unified treatment for transformations studied by Lyapunov, Stein, Lim, Hiller and Johnson, and others. Our method actually works in a more general setting of proper cones and, in particular, on symmetric cones in Euclidean
Jordan algebras.

\begin{abstract}
Invertibility of all convex combinations of a matrix $A$ and the identity matrix $I$ is equivalent to the real eigenvalues of $A$, if any, being positive. Invertibility of all matrices whose rows are convex combinations of the respective rows of $A$ and $I$ is equivalent to all of the principal minors of $A$ being positive (i.e., $A$ being a P-matrix). These results are
extended to convex combinations of higher powers of $A$ and of their rows. The invertibility of matrices in these convex hulls is associated with the eigenvalues of $A$ lying in open sectors of the right-half plane. The ensuing analysis provides a new context for open problems in the theory of matrices with P-matrix powers.
