Low-thrust Interplanetary Trajectories with Missed Thrust Events: a Numerical Approach

Jean-Philippe Chancelier, Pierre Carpentier, Guy Cohen +2

The problem under consideration is to drive a spatial vehicle to a target at a given final time while minimizing fuel consumption. This is a classical optimal control problem in a…

Empirical process sampled along a stationary process

Guy Cohen, Jean-Pierre Conze

Let $(X_{ℓ})_{ℓ \in Z^{d}}$ be a real random field (r.f.) indexed by $Z^{d}$ with common probability distribution function $F$ . Let $(z_k)…

$L^{2}$ -Quasi-compact and hyperbounded Markov operators

Guy Cohen, Michael lin

A Markov operator $P$ on a probability space $(S, Σ, μ)$ , with $μ$ invariant, is called {\it hyperbounded} if for some $1 \leq p < q \leq \infty$ it maps (continuously) $L^{p}$ into $L^{q}$ .…

Resolvent conditions and growth of powers of operators on $L^{p}$ spaces

Christophe Cuny

Let $T$ be a bounded linear operator on $L^{p}$ . We study the rate of growth of the norms of the powers of $T$ under resolvent conditions or Cesàro boundedness assumptions. Actually…

Joint and double coboundaries of commuting contractions

Guy Cohen, Michael Lin

Let $T$ and $S$ be commuting contractions on a Banach space $X$ . The elements of $(I - T) (I - S) X$ are called {\it double coboundaries}, and the elements of $(I - T) X \cap (I - S) X$ are ca…

Resolvent conditions and growth of powers of operators

Guy Cohen, Christophe Cuny, Tanja Eisner +1

Following Bermúdez et al. (ArXiv: 1706.03638v1), we study the rate of growth of the norms of the powers of a linear operator, under various resolvent conditions or Cesàro boundedne…
