Researchers have found a new way to solve high-degree polynomial equations, previously thought impossible for 200 years. This math breakthrough reopens algebra.

Based on their degree: second-degree polynomial, such as 4x2, x2 – 9, or ax2 + bx + c, is also called a “quadratic” a third-degree polynomial, such as –6x3 or x3 – 27, is also called a ...

If p(z) is univariate polynomial with complex coefficients having all its zeros inside the closed unit disk, then the Gauss-Lucas theorem states that all zeros of p′(z) lie in the same disk. We study ...

We propose a global smoothing method based on polynomial splines for the estimation of functional coefficient regression models for non-linear time series. Consistency and rate of convergence results ...
