Anisotropic Hölder and Sobolev spaces for hyperbolic diffeomorphisms

Viviane Baladi, Masato Tsujii (2007)

Annales de l’institut Fourier

Similarity:

We study spectral properties of transfer operators for diffeomorphisms T : X X on a Riemannian manifold X . Suppose that Ω is an isolated hyperbolic subset for T , with a compact isolating neighborhood V X . We first introduce Banach spaces of distributions supported on V , which are anisotropic versions of the usual space of C p functions C p ( V ) and of the generalized Sobolev spaces W p , t ( V ) , respectively. We then show that the transfer operators associated to  T and a smooth weight g extend boundedly to these...

Moduli spaces for linear differential equations and the Painlevé equations

Marius van der Put, Masa-Hiko Saito (2009)

Annales de l’institut Fourier

Similarity:

A systematic construction of isomonodromic families of connections of rank two on the Riemann sphere is obtained by considering the analytic Riemann–Hilbert map R H : , where is a moduli space of connections and , , is a moduli space for analytic data (, ordinary monodromy, Stokes matrices and links). The assumption that the fibres of R H (, the isomonodromic families) have dimension one, leads to ten moduli spaces . The induced Painlevé equations are computed explicitly. Except for the...

Sur la régularité des ondes progressives à la surface de l'eau

Walter Craig, Ana-Maria Matei (2003)

Journées équations aux dérivées partielles

Similarity:

Il a été établi par H. Lewy (1952) qu’une surface libre hydrodynamique qui est au moins C 1 dans un voisinage d’un point q à la surface libre, est automatiquement C ω , éventuellement dans un voisinage plus petit de q . Ce résultat local est un exemple qui précédait la théorie dévelopée par D. Kinderlehrer, L. Nirenberg et J. Spruck (1977 - 79) démontrant que dans beaucoup de cas, des surfaces libres ne peuvent pas être d’une régularité arbitraire, et en particulier ils existent m , α tels que,...
