• Effective bounds for very ample line bundles AI翻译
  作者：Demailly, JP
  摘要：Let L be an ample line bundle on a non singular projective n-fold X. It is first shown that 2K(X) + mL is very ample for m greater than or equal to 2 + ((3n+1)(n)). The proof develops an original idea of Y.T. Siu and is based on a combination of the Riemann-Roch theorem together with an improved Noetherian induction technique for the Nadel multiplier ideal sheaves. In the second part, an effective version of the big Matsusaka theorem is obtained, refining an earlier version of Y.T. Siu: there ...
• On the convergence of circle packings to the Riemann map AI翻译

  作者单位：Weizmann Institute of Science
  摘要：Rodin and Sullivan (1987) proved Thurston's conjecture that a scheme based on the Circle Packing Theorem converges to the Riemann mapping, thereby providing a refreshing geometric view of Riemann's Mapping Theorem. We now present a new proof of the Rodin-Sullivan theorem. This proof is based on the argument principle, and has the following virtues. 1. It applies to more general packings. The Rodin-Sullivan paper deals with packings based on the hexagonal combinatorics. Later, quantitative esti...

• Strange attractors in saddle-node cycles: Prevalence and globality AI翻译
  作者：Diaz, LJ; Rocha, J; Viana, M
  作者单位：Universidade do Porto; Instituto Nacional de Matematica Pura e Aplicada (IMPA)
  摘要：We consider parametrized families of diffeomorphisms bifurcating through the creation of critical saddle-node cycles. We show that they always exhibit Henon-like strange attractors for a set of parameter values with positive Lebesgue density at the bifurcation value. Zn open classes of such families the strange attractors are of global type: their basins contain an a priori defined neighbourhood of the cycle. Furthermore, the bifurcation parameter may also be a point of positive density of hyp...

• DEFINITIONS OF QUASICONFORMALITY AI翻译
  作者：HEINONEN, J; KOSKELA, P
  摘要：We establish that the infinitesimal ''H-definition'' for quasiconformal mappings on Carnot groups implies global quasisymmetry, and hence the absolute continuity on almost all lines. Our method is new even in R(n) where we obtain that the ''limsup'' condition in the H-definition can be replaced by a ''liminf'' condition. This leads to a new removability result for (quasi)conformal mappings in Euclidean spaces. An application to parametrizations of chord-are surfaces is also given.
• LIFT ACCORDING TO AN ISOGENY OF 1-ADIC SYSTEMS OF GALOIS REPRESENTATIONS ASSOCIATED WITH MOTIFS AI翻译
  作者：WINTENBERGER, JP
  作者单位：Universites de Strasbourg Etablissements Associes; Universite de Strasbourg; Centre National de la Recherche Scientifique (CNRS)
  摘要：Let rho(l) : G(E) --> H(Q(l)) be a system of l-adic Galois representations associated to a motive over a number field E with values in the algebraic group H. Let H' --> H be a central isogeny such that the complex Hedge structure lifts to H'. The main result is that, under some convenient hypothesis, and after restriction to a finite extension, the system of Galois representations lifts to H'.
