The optimization problems of a quadratic Hermitian matrix-valued function with the constraint of matrix equations Yawen Lan, Honglin Zou and Yongxin Yuan Filomat , pp. 8813-8826 (14 pages) ...

A mathematician at Carnegie Mellon University has developed an easier way to solve quadratic equations. Here's the secret.

In a boon to algebra students everywhere, a professor at Carnegie Mellon University has devised a simpler and more efficient way to solve problems involving the quadratic equation.

We analyze two popular semidefinite programming relaxations for quadratically constrained quadratic programs with matrix variables. These relaxations are based on vector lifting and on matrix lifting; ...
