چکیده
O autor analisa as clivagens nacionalistas que favoreceram a associação do expressionismo ao caráter trans-histórico da arte alemã, questionando tendência considerar, sem exame prévio, o como designação vanguarda alemã entre 1905 e 1920-1923. próprio expressionismo, englobando diferentes tendências fronteiras geográficas precisas, caracteriza-se pelo distanciamento formal, espacial temporal de natureza, opondo-se à imediatez impressionismo.

Spectral Statistics on Zoll Surfaces
The subject of this article is a family of (partly conjectural) spectral invariants of a Laplace operator with a discrete spectrum 2j known as its k-level correlation functions Pk and level spacings distribution v. The 2-level (or pair) correlation function P2, for instance, measures the asymptotic number of spacings 2* 2* between normalized eigenvalues 2* as the eigenvalues tend to infinity. T...
متن کاملZoll Manifolds and Complex Surfaces
We classify compact surfaces with torsion-free affine connections for which every geodesic is a simple closed curve. In the process, we obtain completely new proofs of all the major results [4] concerning the Riemannian case. In contrast to previous work, our approach is twistor-theoretic, and depends fundamentally on the fact that, up to biholomorphism, there is only one complex structure on CP2.
متن کاملA Zoll Counterexample to a Geodesic Length Conjecture
We construct a counterexample to a conjectured inequality L ≤ 2D, relating the diameter D and the least length L of a nontrivial closed geodesic, for a Riemannian metric on the 2sphere. The construction relies on Guillemin’s theorem concerning the existence of Zoll surfaces integrating an arbitrary infinitesimal odd deformation of the round metric. Thus the round metric is not optimal for the r...
متن کاملLower Order Terms in Szegö Theorems on Zoll Manifolds
We give an outline of the computation of the third order term in a generalization of the Strong Szegö Limit Theorem for a zeroth order pseudodifferential operator (PsDO) on a Zoll manifold of an arbitrary dimension, see [Gi2] for the detailed proof. This is a refinement of a result by V. Guillemin and K. Okikiolu who have computed the second order term in [GO2]. An important role in our proof i...
متن کاملThe Quintic Nonlinear Schrödinger Equation on Three-dimensional Zoll Manifolds
Let (M, g) be a three-dimensional smooth compact Riemannian manifold such that all geodesics are simple and closed with a common minimal period, such as the 3-sphere S with canonical metric. In this work the global well-posedness problem for the quintic nonlinear Schrödinger equation i∂tu+∆u = ±|u|u, u|t=0 = u0 is solved for small initial data u0 in the energy space H(M), which is the scaling-c...
