Differential equation is very important in science and engineering, because it required the description of some measurable quantities (position, temperature, population, concentration, electrical ...

Abstract: One of the foundational principles of optimal control theory is that optimal control laws are propagated backward in time. For linear-quadratic control, this means that the solution of the ...

ABSTRACT: In this work, we study the existence and uniqueness of pseudo almost periodic solutions for some difference equations. Firstly, we investigate the spectrum of the shift operator on the space ...
