摘要:We classify all weak * limits of squares of normalized eigenfunctions of the Laplacian on two-dimensional flat tori (called quantum limits). We also obtain several results about such limits in dimensions three and higher. Many of the results are a consequence of a geometric lemma which describes a property of simplices of codimension one in R-n whose vertices are lattice points on spheres. The lemma follows from the finiteness of the number of solutions of a system of two Pell equations. A con...

摘要:Let G be a finite extension of a torus. WVorking with highly structured ring and module spectra, let M be any module over MU; examples include all of the standard homotopical MU-modules, such as the Brown-Peterson and Morava K-theory spectra. We shall prove localization and completion theorems for the computation of M*(BG) and M*(BG). The G-spectrum MUG that represents stabilized equivariant complex cobordism is an algebra over the equivariant sphere spectrum S-G, and there is an MUG-module M-...

摘要:The central result of this paper is a generalization of the Ehresmann fibration theorem to the infinite-dimensional and/or non-proper setting. With this aim, we introduce the concepts of strong submersion and of mapping with uniformly split kernels. First applications include a global Implicit Function Theorem and a necessary and sufficient version of Hadamard's global invertibility criterion in the setting of Finsler manifolds. Another major application makes use of the idea of asymptotic cri...
