The discriminant — From a quadratic equation to dynamic nonlinear systems
… Usually discussed while learning the Quadratic Formula to solve quadratic equations, students learn its use for the classification of type and number of solutions for each equation being solved. Most students memorize the formula, identify the correct values for each variable, and …

A factorization approach for solving the Hamilton-Jacobi equations in nonlinear optimal control
The Hamilton-Jacobi equation (HJE) arose early in the last century in the study of the calculus of variation, classical mechanics and Hamiltonian systems. Recently, there has been a renewed interest in HJEs arising in various analysis and synthesis problems in systems theory. The HJE despite …
