Belmont Professsor of Mathematics Danny Biles , Marcia Federson of University of Sao Paulo in Brazil and Rodrigo Lopez Pouso of University of Santiago de Compostela in Spain had a paper accepted for publication by the journal Abstract and Applied Analysis. The paper is titled “A Survey of Recent Results in the Generalizations of Ordinary Differential Equations.” Abstract and Applied Analysis is a mathematical journal devoted exclusively to the publication of high-quality research papers in the fields of abstract and applied analysis. Emphasis is placed on important developments in classical analysis, linear and nonlinear functional analysis, ordinary and partial differential equations, optimization theory and control theory. The journal supports the publication of original material involving the complete solution of significant problems in the above disciplines. Abstract and Applied Analysis also encourages the publication of timely and thorough survey articles on current trends in the theory and applications of analysis.
