\vskip 1truecm

\noindent
Prof.$\,$M.Marinaro offers to supervise one postdoctoral fellow for a 
period of 12 months. The activity will be theoretical and based on the 
use of Quantum Field Theory methods applied to Condensed Matter Physics.

\noindent
The fellow will work in a group of 4 experienced people, which 
collaborate with other scientists, such as Prof.$\,$H.Matsumoto (Sendai, 
Japan), Prof.$\,$R.Micnas (Poznan, Poland), Prof.$\,$G.Iadonisi (Naples, 
Italy).

The activity proposed to the perspective fellow is the following:

{\bf Name of activity}

\item {} Electronic states in normal and superconducting systems 
with strong correlations

\vskip 0.2truecm
\noindent
{\bf Objectives of activity}

\item {} The physical properties of systems with strong electronic 
correlations have been so far studied within the framework of the 
periodic Anderson model, by means of a perturbative expansion in the 
kinetic term of the conduction electrons. Special attention has been 
devoted to the structure of the electronic density of states and to the 
study of the singlet and triplet superconducting solutions generated by 
the inclusion of an attractive off-site interaction between correlated 
electrons.

\item {} The continuation of this kind of analysis and the application 
of similar techniques to other correlated electron models, such as those 
used in the theory of high-$T_c$ superconductors, represents the research 
activity planned for the next future.

\vskip 1truecm

\noindent
Prof.$\,$E.R.Caianiello offers to supervise one postdoctoral fellow for a 
period of 12 months. The activity will be mainly experimental and based on 
the use of Neural Networks for adaptive signal processing and feature 
extraction.

\noindent
The fellow will work in a group of 5 experienced people, which 
collaborate with other scientists, coming from the Universities of Rome 
and Pavia, IRST of Trento, MIT of Boston.

\item {} Neural Networks for Signal Processing

\vskip 0.2truecm
\noindent
{\bf Objectives of activity}

\item {} Study of learning in neural networks to obtain the best 
performances in complex hybrid systems for signal processing. The nets 
are used in the phases of filtering, feature extraction and 
classification either for speech processing or for 2D pattern 
recognition.

Prof.$\,$F.Mancini offers to supervise one postdoctoral fellow for a 
period of 12 months. The activity will be theoretical and based on the 
use of Quantum Field Theory techniques applied to Condensed Matter Physics.

The research project is a part of a common program between the 
Institute of Materials Research at Tohoku University, Sendai (Japan) and 
the Department of Theoretical Physics at the University of Salerno.

The activity proposed to the perspective fellow is the following:

\vskip 0.2truecm
\noindent
{\bf Name of activity}

\vskip 0.2truecm
\item {} Superconductivity at high critical temperature

\vskip 0.2truecm
\noindent
{\bf Objectives of activity}

\item {} The phenomenon of superconductivity in the new materials which 
exhibit a high critical temperature is still not well understood from 
a theoretical point of view. By making use of the p-d model, our purpose 
is to investigate the fundamental mechanism which induces 
superconductivity in the new superconductor oxides. At first stage, the 
theoretical effort is concentrated on understanding the electronic 
structure realized in proximity of the metal-insulator transition.
