Hilbert Schemes as Moduli of Higgs Bundles and Local Systems
We construct five families of 2D moduli spaces of parabolic Higgs bundles (respectively, local systems) by taking the equivariant Hilbert scheme of a certain finite group acting on the cotangent bundle of an elliptic curve (respectively, twisted cotangent ...
Oxford University Press2014On Singular Poisson Sternberg Spaces
We obtain a theory of stratified Sternberg spaces thereby extending the theory of cotangent bundle reduction for free actions to the singular case where the action on the base manifold consists of only one orbit type. We find that the symplectic reduced sp ...
2009Patrimoine, énergie, économie : conservation préventive et amélioration thermique des enveloppes de la Cité satellite du Lignon à Genève (1963-1971)
Built between 1963 and 1971, the Lignon satellite precinct in Geneva (Georges Addor, Dominique Julliard, Louis Payot, Jacques Bolliger architects) is regarded as the most spectacular housing development in post-war Switzerland. The heritage protection agen ...
SCR/SKR2009Some applications of symmetries in differential geometry and dynamical systems
This thesis deals with applications of Lie symmetries in differential geometry and dynamical systems. The first chapter of the thesis studies the singular reduction of symmetries of cosphere bundles, the conservation properties of contact systems and their ...
EPFL2007Topological defects and gravity in theories with extra dimensions
Recent proposals of large and infinite extra dimensions triggered a strong research activity in theories in which our universe is considered as a sub-manifold of some higher-dimensional space-time, a so-called 3-brane. In this context, it is generally assu ...
