      <Abstract>A category is an algebraic structure made up of a collection of objects linked together by morphisms. As a foundation of mathematics, categories were created as a way of relating algebraic structures and systems of topological spaces In this paper we define a derivative using cones in the category of topological modules and use the Lagrange__ampersandsignrsquo;s principle to obtain optimization results in the category</Abstract>
