Abstract: This paper proposes a new local polynomial modeling based variable forgetting factor (VFF) and variable regularized (VR) projection approximation subspace tracking (PAST) algorithm, which is ...

Is your feature request related to a problem? Please describe. I came across a missing special case for factoring polynomials in FLINT while using it in Mathematica, which causes such factoring to ...

A mathematician at Carnegie Mellon University has developed an easier way to solve quadratic equations. The mathematician hopes this method will help students avoid memorizing obtuse formulas. His ...

Two mathematicians have used a new geometric approach in order to address a very old problem in algebra. In school, we often learn how to multiply out and factor polynomial equations like (x² – 1) or ...

We study real-life problems via mathematical models, which usually tend to be nonlinear systems, or equations. A standard trick is to “linearize” this nonlinear system. The newly obtained system then ...

In this paper, an algebraic method which is based on the groebner bases theory is proposed to solve the polynomial functions conditional extreme. Firstly, we describe how to solve conditional extreme ...
