The purpose of this note is to obtain rational criteria for diagonalizability of real matrices through the analysis of the moment and Gram matrices associated to a given real matrix. These concepts were introduced by Horn and Lopatin in [R.A. Horn an

This paper proposes a wireless remote RGB-D visual SLAM solution for low computational powered robots. We develop a ROS implementation of the tools necessary to send RGB-D images over wireless networks. Making use of state-of-the-art compression tech

For an interval map, the poles of the Artin-Mazur zeta function providetopological invariants which are closely connected to topological entropy. Itis known that for a time-periodic nonautonomous dynamical system F withperiod p, the p-th power [ζ F

Infinite order linear recurrences are studied via kneading matrices and kneading determinants. The concepts of kneading matrix and kneading determinant of an infinite order linear recurrence, introduced in this work, are defined in a purely linear al

Infinite Leslie matrices, introduced by Demetrius 40 years ago, are mathematical models of age-structured populations defined by a countable infinite number of age classes. This article is concerned with determining solutions of the discrete dynamica

In the setting of continuous piecewise monotone interval maps, we study the analytic properties of the zeta function of a periodic nonautonomous dynamical system. Based upon these properties we discuss the relationship between topological entropy and
