We describe the structure of all codimension-2 lattice configurations A which admit a stable rational A-hypergeometric function, that is a rational function F all the partial derivatives of which are nonzero, and which is ...

This research proposes the teaching of mathematics in the secondary school by means of the Study and Research Paths (SRP). A longitudinal analysis has been carried out during two years with secondary school students (aged ...

In the late seventies, Megiddo proposed a way to use an algorithm for the problem of minimizing a linear function a(0) + a(1)x(1) + ... + a(n)x(n) subject to certain constraints to solve the problem of minimizing a rational ...

This study proposes an alternative method to calculate the transient responses of multi-conductor overhead transmission lines based on ABCD representation, recursive convolutions and numerical method for rational approximation ...

We present a solution for the classical univariate rational interpolation problem by means of (univariate) subresultants. In the case of Cauchy interpolation (interpolation without multiplicities), we give explicit formulas ...

The TKSAMC is a web server which calculates protein charge–charge interactions via the Tanford–Kirkwood Surface Accessibility model with the Monte Carlo method for sampling different protein protonation states. The ...

The local existence of the Borel transform of a two-dimensional field theoretical model characterized by the rational interaction g2x 6/(1 + gx2) is proven. © 1989 American Institute of Physics.

We consider an infinite family of non-rational conformal field theories in the presence of a conformal boundary. These theories, which have been recently proposed in [1], are parameterized by two real numbers (b,m) in such ...
