Bergman kernel and stability of holomorphic vector bundles with sections
… on a projective manifold. We prove that the special metric on the bundle studied by Bradlow is the limit of a sequence of balanced metrics that are induced from the asymptotic stability. Conversely, assuming the convergence of a sequence of balanced metrics, we show that the sequence converge …

Rankings: From similarity distances computation to interactive synchronization
… Our focus is on costs that may be described via special metric-tree structures and on full rankings modeled as permutations. The presented results include a quadratic-time algorithm for finding a minimum cost trans- form for simple cycles; and a linear time, 5/3-approximation algorithm for …

SPECIAL RIEMANNIAN STRUCTURES ON FOUR-MANIFOLDS: FROM TWISTOR SPACES TO UNOBSTRUCTED CONDITIONS
This thesis deals with special Riemannian metrics on smooth manifolds: in particular, we study the relations between the existence of metrics satisfying curvature properties and the topology of the manifold they are defined on. In the first part of the work, we introduce Riemannian twistor spaces, …
