Locality and Bell's inequality
We prove that the locality condition is irrelevant to Bell in equality. We
check that the real origin of the Bell's inequality is the assumption of
applicability of classical (Kolmogorovian) probability theory to quantum
mechanics. We describe the chameleon effect which allows to construct an
experiment realizing a local, realistic, classical, deterministic and
macroscopic violation of the Bell inequalities.Comment: 23 pages, Plain TeX, A talk given at Capri conference, July 2000,

Separable solutions of quasilinear Lane-Emden equations
For and , we prove the existence of solutions of
-\Gd_pu=\ge u^q in a cone , with vertex 0 and opening , vanishing on
\prt C_S, under the form u(x)=|x|^\gb\gw(\frac{x}{|x|}). The problem
reduces to a quasilinear elliptic equation on and existence is based upon
degree theory and homotopy methods. We also obtain a non-existence result in
some critical case by an integral type identity.Comment: To appear in Journal of the European Mathematical Societ
The full coverage approach to the detection of Extensive Air Showers
A shower array exploiting the full coverage approach with a high segmentation
of the readout allow to image the front of atmospheric showers with
unprecedented resolution and detail. The grid distance determines the energy
threshold (small energy showers are lost in the gap between detectors) and the
quality of the shower sampling. Therefore, this experimental solution is needed
to detect showers with a threshold in the 100 GeV range. The full coverage
approach has been exploited in the ARGO-YBJ experiment. In this contribution we
will summarise the advantages of this technique and discuss possible
applications in new wide field of view detectors.Comment: Invited Talk to 21st International Symposium on Very High Energy
