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.

    The representation of weighted quasimetric spaces
    (Università degli Studi di Trieste. Dipartimento di Scienze Matematiche, 1999)
    Vitolo, Paolo
    We show that every weighted quasi-metric space can be identified with a subspace of a space of some canonical type, which is constructed from a metric space. We also present a very simple method to construct a weighted quasi-metric space, as the graph of a function defined on a metric space, and show that every weighted quasi-metric space arises in this way. Similar results may be obtained if we drop the requirement that the weight function have nonnegative values.

    We construct a class of quaternionic Kähler structures on the tangent bundle of a complex space form of dimension 2n(n > 2), giving a generalization of the result in [13].

    Multi valued analytic functionals on compact Riemann surfaces of genus $g\geq 1$
    (Università degli Studi di Trieste. Dipartimento di Scienze Matematiche, 1999)
    Sabadini, Irene
    In this paper we study analytic functionals on compact Riemann surfaces of genus $g\geq 1$, from the modern point of view of hyperfunctions. We will give some topological duality theorems and an integral representation for these functionals.

    (Università degli Studi di Trieste. Dipartimento di Scienze Matematiche, 1999)

    ;

    In this paper we give two compact spaces X, Y with dim(X) = dim(Y) = 1, ind(X) = ind(Y) = Ind(X) = Ind(Y) = 3, where dim is the covering dimension, ind and Ind are the small and large inductive dimensions respectively.
