Abstract
We obtain inner estimations, around special eigenvalues, for the eigenvalue set of a properly
nonlinear closed convex process. We also consider a differential inclusion associated with a
general closed convex process and we construct smooth power series solutions of exponential
type for some initial states.
Key words: convex process, eigenvalues, differential inclusion.
1 Introduction
Set-valued analysis is a flexible framework which permits to treat in a unified manner a wide
variety of applications, ranging from equilibrium problems in theoretical economics to the control
of dynamical systems. Although multivalued maps share some properties with their singlevalued
analogues, the set-valued structure gives rise to important differences in many aspects of the theory.
A particularly interesting multivalued concept is that of convex process on a vector space, that is,
a set-valued map whose graph is a convex cone containing the origin. This natural generalization
of a linear transformation was first introduced by Rockafellar [8, 9], and since his pioneering work
