The role of Coulomb interaction in fragmentation

M. J. Ison, C. O. Dorso

We examine the impact of adding a Coulomb term to a constrained system of 147 particles interacting via a Lennard-Jones (LJ) potential, finding that the inclusion of the coulombic…

A new condition to identify isotropic dielectric-magnetic materials displaying negative phase velocity

R. A. Depine, A. Lakhtakia

The derivation of a new condition for characterizing isotropic dielectric-magnetic materials exhibiting negative phase velocity, and the equivalence of that condition with previous…

Some Bounds for the Number of Components of Real Zero Sets of Sparse Polynomials

Daniel Perrucci

We prove that the zero set of a 4-nomial in n variables in the positive orthant has at most three connected components. This bound, which does not depend on the degree of the polyn…

Codimension Theorems for Complete Toric Varieties

David Cox, Alicia Dickenstein

Let X be a complete toric variety with homogeneous coordinate ring S. In this article, we compute upper and lower bounds for the codimension in the critical degree of ideals of S g…

Bivariate hypergeometric D-modules

Alicia Dickenstein, Laura Matusevich, Timur Sadykov

We undertake the study of bivariate Horn systems for generic parameters. We prove that these hypergeometric systems are holonomic, and we provide an explicit formula for their holo…

A formula for the central value of certain Hecke L-functions

Ariel Pacetti

Let N = 1 mod 4 be the negative of a prime, K=Q(sqrt{N}) and O_K its ring of integers. Let D be a prime ideal in O_K of prime norm congruent to 3 modulo 4. Under these assumptions,…
