We consider a class of variational
problems for differential inclusions, related to the
control of wild fires. The area burned by the fire at time t> 0
is modelled as the reachable set for
a differential inclusion ∈F(x), starting from
an initial set R0. To block the fire, a barrier can be constructed
progressively in time. For each t> 0, the portion of the wall constructed
within time t is described by a rectifiable set
γ(t) ⊂. In this paper
we show that the search

The paper studies the problem of exact controllability of the Euler- Bernoulli equation in a cylinder of , via boundary controls acting on its lateral surface.
The notions of externally and internally positive time-varying linear systems are introduced. Necessary and sufficient conditions for the external and internal positivities of time-varying linear systems are established. Moreover, sufficient conditions for the reachability of internally positive time-varying linear systems are presented.
