The Handbook of Linear Algebra provides comprehensive coverage of linear algebra
concepts, applications, and computational software packages in an easy-to-use handbook …

This monograph presents a collection of results, observations, and examples related to
dynamical systems described by linear and nonlinear ordinary differential and difference …

This paper deals with the notion of output strictly negative-imaginary systems. A definition is
given for the class of output strictly negative-imaginary systems and a lemma is proposed to …

We study Gleason's problem, rational functions and spaces of regular functions in the setting
of split-quaternions. There are two natural symmetries in the algebra of split-quaternions …

This expository article presents an overview of research, conducted mostly between the mid-
1990s and late 2000s, that explores a link between commutation relations among a family of …

In this paper we study classical spaces of analytic functions which are convex cones and
closed under the involution f→ 1/f. These include the spaces of positive real, positive real …

A sufficient condition for the existence of a Lyapunov function of the form V (x)= x Tx P, P=
PT> 0, P∈ R n× n, for the stable linear time invariant systems ẋ= i A x, i A∈ R n× n, i A∈ …

In the paper [CL1] the notion of a convex invertible cone, cic, of matrices was introduced and
its geometry was studied. In that paper close connections were drawn between this cic …
