Forh=1 we construct a compact dynamical system which is minimal and has the topological entropyh, but which does not carry any ergodic measure with entropyh. The method works for anyh(0<h ). It is an extension of the method used for the construction in [1], section 27. 相似文献

Résumé Le lemme de Brody est un outil de base en hyperbolicité complexe. On en présente une version précisant la localisation d’une
courbe entière issue d’une suite divergente de disques holomorphes. Elle donne aussi une caractérisation de l’hyperbolicité
en termes d’inégalité isopérimétrique. 相似文献

Summary The purpose of this paper is to prove that Strassen's algorithm is a representation of a product of (2,2) matrices by a Hadamard product in a space of 7 dimensions. For matrices (n, n) it is possible to obtain this representation in spaces withn
3–n+1 dimensions. 相似文献

We prove the existence of a first non-trivial curve in the Fucik spectrum of the p-Laplacian. This yields in particular a variational characterization of the second eigenvalue of the p-Laplacian by a mountain pass procedure. An application to the study of the existence of solution for an equation of the form −Δpu = ƒ(x,u) is given. 相似文献

We show that the sufficient conditions given by Cahen, Grazzini and Haouat for a version of the Stone-Weierstrass theorem in commutative algebra are the widest. More precisely, letA be a Noetherian ring andI a proper ideal ofA such thatA is Hausdorff with respect to theI-adic topology. Note the completion ofA andC(Â,Â) the ring of continuous functions from to with uniform convergence topology. The subset of polynomial functions is dense inC(Â,Â) if and only if the radical ofI is a maximal idealm ofA and the local ringA m is a one-dimensional analytically irreducible domain with finite residue field. 相似文献

In this paper, we reduce the Levi Problem for open sets in a locally trivial holomorphic bundle on a Stein manifold with compact homogeneous fibre, to the Levi Problem in the fibres of the bundle. 相似文献
