Optimal control theory for differential equations is a pivotal discipline that combines rigorous mathematical analysis with practical applications in engineering, economics, and the natural sciences.

Optimal control theory provides a rigorous mathematical framework for determining control policies that guide dynamical systems towards a desired performance, often by minimising an associated cost ...

A pair of mathematicians have proposed a unified theory of dark matter and dark energy that alters Einstein's equations describing the fundamentals of gravity. They suggest the law of energy and ...
