abstract = {We introduce a new noninterference policy to capture the class of functions computable in polynomial time on an object-oriented programming language. This policy makes a clear separation between the standard noninterference techniques for the control flow and the layering properties required to ensure that each “security” level preserves polynomial time soundness, and is thus very powerful as for the class of programs it can capture. This new characterization is a proper extension of existing tractable characterizations of polynomial time based on safe recursion. Despite the fact that this noninterference policy is Π10-complete, we show that it can be instantiated to some decidable and conservative instance using shape analysis techniques.},

power of Lipschitz dynamical systems which are robust to
infinitesimal perturbations.  Whereas the study in [1] was done
only for not-so-natural systems from a classical mathematical
point of view (discontinuous differential equation systems,
discontinuous piecewise affine maps, or perturbed Turing
machines), we prove that the results presented there can be
generalized to Lipschitz and computable dynamical systems.  In
other words, we prove that the perturbed reachability problem
(i.e. the reachability problem for systems which are subjected
to infinitesimal perturbations) is co-recursively enumerable
for this kind of systems.  Using this result we show that if
robustness to infinitesimal perturbations is also required, the
reachability problem becomes decidable. This result can be
interpreted in the following manner: undecidability of
verification doesn't hold for Lipschitz, computable and robust
systems.  We also show that the perturbed reachability problem
is co-r.e.  complete even for C$\infty$-systems.},

abstract = {{A} computing system can be modelized in
various ways: one being in analogy with transfer functions,
this is a function that associates to an input and optionally
some internal states, an output ; another being focused on the
behaviour of the system, that is describing the sequence of
states the system will follow to get from this input to produce
the output. {T}his second kind of system can be defined by
dynamical systems. {T}hey indeed describe the local''
behaviour of a system by associating a configuration of the
system to the next configuration. {I}t is obviously interesting
to get an idea of the global'' behaviour of such a dynamical
system. {T}he questions that it raises can be for example
related to the reachability of a certain configuration or set
of configurations or to the computation of the points that will
be visited infinitely often. {T}hose questions are
unfortunately very complex: they are in most cases undecidable.

dynamical systems and exhibit some results on decidability and
undecidability in various kinds of dynamical systems.},

matter to study the global and the limit behaviour of such systems.
A possible description of this limit behaviour is via the
omega-limit set: the set of points that can be limit of
subtrajectories. The omega-limit set is in general uncomputable. It
can be a set highly difficult to apprehend. Some systems have for
example a fractal omega-limit set. However, in some specific cases,
this set can be computed. This problem is important to verify
properties of dynamical systems, in particular to predict its
collapse or its infinite expansion.  We prove in this paper that
for linear continuous time dynamical systems, it is in fact
computable. More, we also prove that the $\omega$-limit set is
a semi-algebraic set. The algorithm to compute this set can
easily be derived from this proof.},

Unfortunately, most models are not equivalent. Euler's Gamma
function, which is computable according to computable analysis, but
that cannot be generated by Shannon's General Purpose Analog
Computer (GPAC), has often been used to argue that the GPAC is less
powerful than digital computation. However, when computability with
GPACs is not restricted to real-time generation of functions, it
has been shown recently that Gamma becomes computable by a GPAC.
Here we extend this result by showing that, in an appropriate
framework, the GPAC and computable analysis are actually equivalent
from the computability point of view, at least in compact
intervals. Since GPACs are equivalent to systems of polynomial
differential equations then we show that all real computable
functions over compact intervals can be defined by such models.},

computable functions over the integers have been proved to correspond
to the smallest class of real functions containing some basic
functions and closed by composition and linear integration. We
extend this result to all computable functions: functions over the
reals that extend total recursive functions over the integers are
proved to correspond to the smallest class of real functions
containing some basic functions and closed by composition, linear
integration and a very natural unique minimization schema.}

of the Grzegorczyk Hierarchy. This paper improves several previous
partial characterizations and has a dual interest:
* Concerning recursive analysis, our results provide
machine-independent characterizations of natural classes of
computable functions over the real numbers, allowing to define
these classes without usual considerations on higher-order (type 2)
Turing machines.
* Concerning analog models, our results provide a characterization
of the power of a natural class of analog models over the real
numbers and provide new insights for understanding the relations
between several analog computational models.},
