Editorial policy The journal Rendiconti dell’Istituto di Matematica dell’università di Trieste publishes original articles in all areas of mathematics. Special regard is given to research papers, but attractive expository papers may also be considered for publication. The journal usually appears in one issue per year. Additional issues may however be published. In particular, the Managing Editors may consider the publication of supplementary volumes related to some special events, like conferences, workshops, and advanced schools. All submitted papers will be refereed. Manuscripts are accepted for review with the understanding that the work has not been published before and is not under consideration for publication elsewhere. Our journal can be obtained by exchange agreements with other similar journals.

Instructions for Authors Authors are invited to submit their papers by e-mail directly to one of the Managing Editors in PDF format. All the correspondence regarding the submission and the editorial process of the paper are done by e-mail. Papers have to be written in one of the following languages: English, French, German, or Italian. Abstracts should not exceed ten printed lines, except for papers written in French, German, or Italian, for which an extended English summary is required. After acceptance, manuscripts have to be prepared in LaTeX using the style rendiconti.cls which can be downloaded from the web page. Any figure should be recorded in a single PDF, PS (PostScript), or EPS (Encapsulated PostScript) file.

Low Frequency Electromagnetic Scattering. The Impedance Problem for a Spere
(Università degli Studi di Trieste. Dipartimento di Scienze Matematiche, 2001)
Venkov, George

Arnaoudov, Yani
We consider the low-frequency scattering problem of a plane electromagnetic wave by a small sphere, of the boundary of which an impedance condition is satisfied. The impedance boundary condition was introduced by Leontovich (1948) and it accounts for situations where the obstacle is not perfectly conducting but the exterior field will not penetrate deeply into the scatterer. Il provides a method to simulate the material properties of the surface of highly absorbing coating layers. For the near electromagnetic field we obtain the low-frequency coefficients of the zeroth and the first order while in the far field we derive the leading non-vanishing terms for the scattering amplitude, the scattering and the absorption cross-sections.

Singular semilinear elliptic equations in the half-space
(Università degli Studi di Trieste. Dipartimento di Scienze Matematiche, 2001)
Tintarev, Kyril
We show that equation $x_{N}^{q}\Delta u+u^{p-1}=0$ on the half-space $Y=\mathbf{R}^{N-1}\times\left(0,\infty\right)$ and on some of its subsets has a ground state solution for $q=N-\frac{p\left(N-2\right)}{2},\; p\;\epsilon\left(2,2*\right)$. For N $\geq$ 3 the end point cases p=2 and p=2{*} correspond to eh Hardy inequality and the limit exponent Sobolev inequality respectively. For N=2 the problem can be interpreted in terms of Laplace-Beltrami operator on the hyperbolic half-plane.

Special relativity without physics
(Università degli Studi di Trieste. Dipartimento di Scienze Matematiche, 2001)
Pfeffer, Washek F.
Using only causality and the constant speed of light, I derive the Poincaré transformation group. In this derivation I make no a priori assumptions about the linearity or continuity of the transformations

A monomiality principle approach to the Gould-Hopper Polynomials
(Università degli Studi di Trieste. Dipartimento di Scienze Matematiche, 2001)
Noschese, Silvia
We show how to derive properties of the Gould-Hopper polynomials using operational rules associated with the monomiality principle.
