(2009-02-18)An extension of J. Palis’ lambda-lemma is obtained for one case of non-transversal intersection of the stable and unstable manifolds of an hyperbolic fixed point of a C2 local diffeomorphism of R2.
(2012-03-28)Using W. Rudin’s method it is shown that the tauberian theorem can be generalized to several kernels other than the Poisson kernel. We also proof an inverse of the tauberian theorem, that is, an abelian theorem.
(2009-02-18)We show that Hill’s equation with white noise potential has a sequence of Dirichlet eigenvalues /lambda n that behaves almost like in the classical case, in the sense that /lambda n - n2/pi 2 has a logarithmic growth coming ...
