A codimension two stable manifold of near soliton equivariant wave maps

Joachim Krieger, Daniel Tataru

We consider finite-energy equivariant solutions for the wave map problem from ℝ2+1 to S2 which are close to the soliton family. We prove asymptotic orbital stability for a codimension-two class of initial data which is small with respect to a stronger topo ...

Concentration Compactness for critical wave maps

Joachim Krieger

Wave maps are the simplest wave equations taking their values in a Riemannian manifold (M,g). Their Lagrangian is the same as for the scalar equation, the only difference being that lengths are measured with respect to the metric g. By Noether's theorem, s ...

Management of urban energy systems

Mélanie Guittet

In industrialized countries, more than two-thirds of the energy is consumed in urban areas. Hence, energy sobriety calls for special attention to urban planning, especially regarding energy aspects. ...

Contactless energy transfer with Induction for a miniature Car

Contactless energy transfer is very promising in terms of property and handling. In clean rooms contactless energy transfer allows to build moving robots without any bending cable that emits particles with every movement. We want to test one possibility to ...

Models of non-relativistic quantum gravity: the good, the bad and the healthy

Sergey Sibiryakov, Diego Blas Temino

Horava's proposal for non-relativistic quantum gravity introduces a preferred time foliation of space-time which violates the local Lorentz invariance. The foliation is encoded in a dynamical scalar field which we call 'khronon'. The dynamics of the khrono ...

CPT, Lorentz invariance and anomalous clash of symmetries

In this paper we first discuss the analysis regarding the role of Lorentz symmetry in the perturbative non-gravitational anomalies for a family of fermions, which has been recently perfomed in arXiv: 0809.0184. The theory is assumed to be translational inv ...

4d Lorentzian Holst action with topological terms

Danilo Jimenez Rezende

We study the Hamiltonian formulation of the general first order action of general relativity compatible with local Lorentz invariance and background independence. The most general simplectic structure (compatible with diffeomorphism invariance and local Lo ...

Action and influence of the multiple decision levels over the whole energy chain

Matthias Finger, Hans Björn Püttgen, Gaëtan Cherix, Massimiliano Capezzali, Arnaud Chapuis

This study concentrates on determining how to implement the legal framework at different institutional levels in an integrated approach for the planning and management of energy systems in urban areas. There are mainly five levels of decision able to influ ...
