Lagrangian submanifolds in the homogeneous nearly Kähler S3×S3

Bart Dioos, Luc Vrancken, Xianfeng Wang

In this paper, we investigate Lagrangian submanifolds in the homogeneous nearly Kähler S3×S3. We introduce and make use of a triplet of angle functions to describe the geometry of a Lagrangian submanifold in S3×S3. We construct a new example of a flat Lagrangian torus and give a complete...

Stabilization of a Drude/Vacuum Model

Serge Nicaise

We analyze the stability of a dispersive medium immersed in vacuum (with Silver–Müller boundary condition in the exterior boundary) or vice versa. The dispersive medium model corresponds to the coupling between Maxwell’s system and a first order ordinary differential equation (of parabolic type)....

Influence of the w/c ratio on the hydration process of a magnesium phosphate cement and on its retardation by boric acid

Hugo Lahalle, Céline Cau Dit Coumes, Cyrille Mercier, David Lambertin, Céline Cannes, Sylvie Delpech, sandrine Gauffinet

Magnesium potassium phosphate cements (MKPCs) are prepared using calcined magnesia (MgO) and an acidic solution of potassium dihydrogen phosphate (KH2PO4). Their fast setting and high heat of hydration can be problematic when large volumes of materials are produced. Boric acid (B(OH)(3)) is thus...

Properties of the nearly kähler S3×S3

Marilena Moruz, Luc Vrancken

We show how the metric, the almost complex structure and the almost product structure of the homogeneous nearly Kahler S3 × S3 can be recovered from a submersion π : S3 × S3 × S3 → S3 × S3. On S3 × S3 × S3 we have the maps obtained either by changing two coordinates, or by cyclic permutations. We...

New System to Harvest Road Energy Using Piezoelectric Polymers

Chouaib Ennawaoui, Houda Lifi, Abdelowahed Hajjaji, Az-Eddine Azim, Abdessamad Elballouti, Mohamed Rguiti

Green energy is regarded as an essential element for energy production, sustainable development, technological, industrial, and governmental innovations in the world. An increase in the green energy consumption often provides a positive impact on economic growth and social development. A great deal...

Estimates of oscillatory integrals with stationary phase and singular amplitude: Applications to propagation features for dispersive equations

Florent Dewez

In this paper, we study time‐asymptotic propagation phenomena for a class of dispersive equations on the line by exploiting precise estimates of oscillatory integrals. We propose first an extension of the van der Corput Lemma to the case of phases which may have a stationary point of real order and...

Well-posedness and stability results for nonlinear abstract evolution equations with time delays

Serge Nicaise, Cristina Pignotti

We consider abstract evolution equations with a nonlinear term depending on the state and on delayed states. We show that, if the C0 -semigroup describing the linear part of the model is exponentially stable, then the whole system retains this property under some Lipschitz continuity assumptions on...
