This book discusses delay and integro-differential equations from the point of view of the theory of functional differential equations. This book is a collection of selected papers presented at the international conference of Functional Differential Equations and Applications (FDEA-2019), 7th in the series, held at Ariel University, Israel, from August 22–27, 2019. Topics covered in the book include classical properties of functional differential equations as oscillation/non-oscillation, representation of solutions, sign properties of Green's matrices, comparison of solutions, stability, control, analysis of boundary value problems, and applications. The primary audience for this book includes specialists on ordinary, partial and functional differential equations, engineers and doctors dealing with modeling, and researchers in areas of mathematics and engineering.
Alexander Domoshnitsky is Full Professor at the Department of Mathematics and Computer Sciences, Ariel University, Israel, since 2009. Earlier, he was Dean of the Natural Science Faculty at Ariel University, Israel, from 2008–2015. He also was Senior Lecturer and Dozent (Associated Professor) at Perm Polytechnic Institute, Perm, Russia, from 1984–1990. Then he was Senior Lecturer and Associate Professor at the Department of Mathematics and Computer Sciences, Ariel University Center of Samaria, Ariel, Israel, from 1998–2009. He completed his Ph.D. in Mathematics from Tbilisi State University, Tbilisi, Russia, in 1984, and M.Sc. in Mathematics from Perm State University, Russia, in 1979.
His areas of research include non-oscillation, maximum principle, boundary value problems for functional differential equations, theory of functional, stability of integro-differential equations, and theory of impulsive differential equations. He has visited institutions and universities around the globe to deliver invited talks and lectures. Seven students have completed their Ph.D. under his direct supervision. He is Co-author of
Nonoscillation Theory of Functional Differential Equations with Applications (Springer, 2012) and
