Title: An Iterative Method for the Matrix Principal n-th Root<br/><br/>Authors: Lakić, Slobodan<br/><br/>Abstract: In this paper we give an iterative method to compute the principal n-th rootand the principal inverse n-th root of a given matrix. As we shall show thismethod is locally convergent. This method is analyzed and its numerical stabilityis investigated.Radon Measures on Banach Spaces with their Weak Topologies

Title: Radon Measures on Banach Spaces with their Weak Topologies<br/><br/>Authors: Jayne, J.; Rogers, C.<br/><br/>Abstract: The main concern of this paper is to present some improvementsto results on the existence or non-existence of countably additive Borel measuresthat are not Radon measures on Banach spaces taken with their weak topologies, onthe standard axioms (ZFC) of set-theory. However, to put the results in perspective weshall need to say something about consistency results concerning measurable cardinals.Optimization of Discrete-Time, Stochastic Systems

Title: Optimization of Discrete-Time, Stochastic Systems<br/><br/>Authors: Papageorgiou, Nikolaos<br/><br/>Abstract: In this paper we study discrete-time, finite horizon stochastic systemswith multivalued dynamics and obtain a necessary and sufficient condition foroptimality using the dynamic programming method. Then we examine a nonlinearstochastic discrete-time system with feedback control constraints and for it, wederive a necessary and sufficient condition for optimality which we then use toestablish the existence of an optimal policy.<br/><br/>Description: * This research was supported by a grant from the Greek Ministry of Industry and Technology.
