The book "Differential Equations, Discrete Systems and Control" offers a comprehensive introduction to the theory of differential equations as well as control theory for continuous and discrete systems. It is aimed at students with an economic background and conveys mathematical concepts that are relevant for analyzing and solving problems in decision-making. The authors, A. Halanay and J. Samuel, base their teachings on practical experiences from a newly introduced course at the Romanian-American University in Bucharest. This work is an expanded version of the lectures and takes into account the varying levels of prior knowledge among students by linking theory with economic models. Its clear structure and didactic presentation make it a valuable textbook for anyone interested in mathematical models in economics and engineering.
