The purpose of Applied Mathematics Letters is to provide a means of rapid publication for important but brief applied mathematical papers with the best possible typography that a camera-ready publication can provide. It is the intent of the editors to put this journal on the path of continuous evolutionary process insofar as the technicalities of printing and publication are concerned. Our intention is to guarantee that the time elapsed between the receipt of a paper in our editorial offices and publication shall not be more than 90 days on average. The brief descriptions of any work involving a novel application or utilization of mathematics, or a development in the methodology of applied mathematics is a potential contribution for this journal. All areas of mathematics are appropriate: from number theory through Lie algebras to differential games. All application areas are welcome as well, be it computer science, physics, anthropology, fluid dynamics or any other of the main fields of endeavor, where mathematics is used in nontrivial ways.
