Every polynomial is not differentiable at some point, this is known to be the domain or range of that polynomial. The lower range is called the Minima and the upper range is the Maxima of the ...

We study questions related to critical points of the Green's function of a bounded multiply connected domain in the complex plane. The motion of critical points, their limiting positions as the pole ...

The Lee-Yang theorem for the zeroes of the partition function is not strictly applicable to quantum systems because the zeroes are defined in units of the fugacity e^h^@D^@t, and the Euclidean-time ...

Abstract: Minimizing the Euclidean distance (ℓ2 -norm) from a given point to the solution set of a given system of polynomial equations can be accomplished via critical point techniques. This article ...
