Trimodal steady water waves [PDF]
, 2014 We construct three-dimensional families of small-amplitude gravity-driven rotational steady water waves on finite depth. The solutions contain counter-currents and multiple crests in each minimal period.

Segregated vector solutions with multi-scale spikes for nonlinear coupled elliptic systems
Journal of Mathematical Analysis and Applications, 2018 In this paper, we consider the following nonlinear coupled elliptic system ( A e ) { − e 2 Δ u + P ( x ) u = μ 1 u 3 + β u v 2 in R N , − e 2 Δ v + Q ( x ) v = μ 2 v 3 + β u 2 v in R N , u > 0 , v > 0 in R N , u → 0 , v → 0 as | x | → + ∞ , where e >

Topology and Homoclinic Trajectories of Discrete Dynamical Systems [PDF]
, 2012 We show that nontrivial homoclinic trajectories of a family of discrete, nonautonomous, asymptotically hyperbolic systems parametrized by a circle bifurcate from a stationary solution if the asymptotic stable bundles Es(+{\infty}) and Es(-{\infty}) of ...

Symmetrizing quantum dynamics beyond gossip-type algorithms [PDF]
, 2016 Recently, consensus-type problems have been formulated in the quantum domain. Obtaining average quantum consensus consists in the dynamical symmetrization of a multipartite quantum system while preserving the expectation of a given global observable.

Sign-changing blow-up for scalar curvature type equations [PDF]
, 2012 Given $(M,g)$ a compact Riemannian manifold of dimension $n\geq 3$, we are interested in the existence of blowing-up sign-changing families $(\ue)_{\eps>0}\in C^{2,\theta}(M)$, $\theta\in (0,1)$, of solutions to $$\Delta_g \ue+h\ue=|\ue|^{\frac{4}{n-2 ...

, 2010 Recently, a new algorithm for the computation of covariant Lyapunov vectors and of corresponding local Lyapunov exponents has become available. Here we study the properties of these still unfamiliar quantities for a number of simple models, including an ...

Mean field equations on tori: existence and uniqueness of evenly symmetric blow-up solutions [PDF]
, 2019 We are concerned with the blow-up analysis of mean field equations. It has been proven in [6] that solutions blowing-up at the same non-degenerate blow-up set are unique.

Nonlinear Model-Based Control of Unstable Wells [PDF]
, 2007 This paper illustrates the potential of nonlinear model-based control applied for stabilization of unstable flow in oil wells. A simple empirical model is developed that describes the qualitative behavior of the downhole pressure during severe riser ...

Application to light-induced control of open quantum systems [PDF]
, 2011 In linear control, balanced truncation is known as a powerful technique to reduce the state-space dimension of a system. Its basic principle is to identify a subspace of jointly easily controllable and observable states and then to restrict the dynamics ...
