the First Aegean Summer School of Cosmology held on
Samos, Greece, in September 21-29, 2001},

ABSTRACT = { An overview is provided of the singularity theorems
in cosmological contexts at a level suitable for
advanced graduate students. The necessary background
from tensor and causal geometry to understand the
theorems is supplied, the mathematical notion of a
cosmology is described in some detail and issues
related to the range of validity of general
relativity are also discussed.}

TITLE = {Life in an Energy Eigenstate: Decoherent Histories
Analysis of a Model Timeless Universe},

ROPSECTIONS = {COSMOLOGY TIME},
ABSTRACT = {Inspired by quantum cosmology, in which the wave
function of the universe is annihilated by the total
Hamiltonian, we consider the internal dynamics of a
simple particle system in an energy eigenstate. Such
a system does not possess a uniquely defined time
parameter and all physical questions about it must
be posed without reference to time. We consider in
particular the question, what is the probability
that the system's trajectory passes through a set of
regions of configuration space without reference to
time? We first consider the classical case, where
the answer has a variety of forms in terms of a
phase space probability distribution function. We
then consider the quantum case, and we analyze this
question using the decoherent histories approach to
quantum theory, adapted to questions which do not
involve time. When the histories are decoherent, the
probabilities approximately coincide with the
classical case, with the phase space probability
distribution replaced by the Wigner function of the
quantum state. For some initial states, decoherence
requires an environment, and we compute the required
influence functional and examine some of its
properties. Special attention is given to the inner
product used in the construction (the induced or
Rieffel inner product), the construction of class
operators describing the histories, and the extent
to which reparametrization invariance is
respected. Our results indicate that simple systems
without an explicit time parameter may be quantized
using the decoherent histories approach, and the
expected classical limit extracted. The results
support, for simple models, the usual heuristic
proposals for the probability distribution function
associated with a semiclassical wave function
satisfying the Wheeler-DeWitt equation. }

ABSTRACT = {We present the results of a bayesian analysis of
solar neutrino data in terms of \ν$_{ e
}$\&to;\ν$_{\μ,\τ}$ and \ν$_{ e
}$\&to;\ν$_{ s }$ oscillations, where \ν$_{ s
}$ is a sterile neutrino. We perform a Rates
Analysis of the rates of solar neutrino experiments,
including the first SNO CC result, and spectral data
of the CHOOZ experiment, and a Global Analysis that
takes into account also the Super-Kamiokande day and
night electron energy spectra. We show that the
bayesian analysis of solar neutrino data does not
suffer any problem from the inclusion of the
numerous bins of the CHOOZ and Super-Kamiokande
electron energy spectra and allows to reach the same
conclusions on the favored type of neutrino
transitions and on the determination of the most
favored values of the oscillation parameters in both
the Rates and Global Analysis. Our bayesian analysis
shows that \ν$_{ e }$\&to;\ν$_{ s }$
transitions are strongly disfavored with respect to
\ν$_{ e }$\&to;\ν$_{\μ,\τ}$
transitions. In the case of \ν$_{ e
}$\&to;\ν$_{\μ,\τ}$ oscillations, the
Large Mixing Angle region is favored by the data
(86\&percent; probability), the LOW region has some
small chance (13\&percent; probability), the Vacuum
Oscillation region is almost excluded (1\&percent;
probability) and the Small Mixing Angle region is
practically excluded (0.01\&percent;
probability). We calculate also the marginal
posterior probability distributions for tan$^{2}$
\ϑ and \Δ m $^{2}$ in the case of
\ν$_{ e }$\&to;\ν$_{\μ,\τ}$
oscillations and we show that the data imply large
mixing almost with certainty and large values of
\Δ m $^{2}$ are favored (2 $\times$
10$^{\−6}$~eV$^{2}$ $<$ \Δ m $^{2}$ $<$
10$^{\−3}$~eV$^{2}$ with 86\&percent;
probability). We present also the results of a
standard least-squares analysis of solar neutrino
data and we show that the standard goodness of fit
test is not able to reject pure \ν$_{ e
}$\&to;\ν$_{ s }$ transitions. The likelihood
ratio test, which is insensitive to the number of
bins of the CHOOZ and Super-Kamiokande energy
spectra, allows to reject pure \ν$_{ e
}$\&to;\ν$_{ s }$ transitions in favor of
\ν$_{ e }$\&to;\ν$_{\μ,\τ}$ transitions
only in the Global Analysis. }
