Error Analysis on the Initial State Reconstruction Problem

In this paper we propose a method to estimate the initial state of a linear dynamical system with noisy observation. The method allows the user to have estimations in real time, that is, to have a new estimation for each new observation. Moreover, at each step, the covariance matrix of the error is known and it is proved that the dynamic of the state estimator error is always Lyapunov stable. Also, %necessary and sufficient conditions are given to guarantee asymptotic stability for the error dynamics of an LTI dynamical system, which is itself an LTV system.

On the Relative Projective Space

Let $(\mathcal C,\otimes,\mathbb 1)$ be an abelian symmetric monoidal category satisfying certain exactness conditions. In this paper we define a presheaf $\mathbb P^{n}_{\mathcal C}$ on the category of commutative algebras in $\mathcal C$ and we prove that this functor is a $\mathcal C$-scheme in the sense of Toen and Vaquié. This construction gives us a context of non-associative relative algebraic geometry. The most important example of the construction is the octonionic projective space.
