Abstract

Multiplicative and additive DD-stability, diagonal stability, Schur DD-stability, HH-stability are classical concepts which arise in studying linear dynamical systems. We unify these types of stability, as well as many others, in one concept of (D,G,)({\mathfrak D}, {\mathcal G}, \circ)-stability, which depends on a stability region DC{\mathfrak D} \subset {\mathbb C}, a matrix class G{\mathcal G} and a binary matrix operation \circ. This approach allows us to unite several well-known matrix problems and to consider common methods of their analysis. In order to collect these methods, we make a historical review, concentrating on diagonal and DD-stability. We prove some elementary properties of (D,G,)({\mathfrak D}, {\mathcal G}, \circ)-stable matrices, uniting the facts that are common for many partial cases. Basing on the properties of a stability region D\mathfrak D which may be chosen to be a concrete subset of C\mathbb C (e.g. the unit disk) or to belong to a specified type of regions (e.g. LMI regions) we briefly describe the methods of further development of the theory of (D,G,)({\mathfrak D}, {\mathcal G}, \circ)-stability. We mention some applications of the theory of (D,G,)({\mathfrak D}, {\mathcal G}, \circ)-stability to the dynamical systems of different types.
