Skew Loops in Flat Tori
We produce skew loops—loops having no pair of parallel tangent lines—homotopic to any loop in a flat torus or other quotient of Rn . The interesting case here is n = 3 . More subtly for any n , we characterize the homotopy classes that will contain a skew loop having a specified loop τ ⊂ S as tangent indicatrix.
متن کاملThe Euclidean Distortion of Flat Tori
We show that for every n-dimensional lattice L the torus Rn/L can be embedded with distortion O(n ·√log n) into a Hilbert space. This improves the exponential upper bound of O(n) due to Khot and Naor (FOCS 2005, Math. Annal. 2006) and gets close to their lower bound of Ω( √ n). We also obtain tight bounds for certain families of lattices. Our main new ingredient is an embedding that maps any po...
متن کاملPair Correlation of Four-dimensional Flat Tori
1. Introduction. Berry and Tabor conjecture in [1] that the distribution of local spacings between the eigenvalues of the quantization of the Hamiltonian for generic completely integrable systems follows the distribution of local spacings between random numbers. (This is often called the " Poissonian " distribution.) In [5], Sarnak shows that the pair correlations of eigenvalues on almost all t...
متن کاملFrom Convex Integration to Flat Tori
These lectures are devoted to a general method for solving differential relations: the Gromov Convex Integration Theory. We explore its simple version for first order differential relations with special attention to its geometrical and analytical foundations (Lecture 1). We introduce the notion of h-principle and then prove by using Convex Integrations that the h-principle holds for ample and o...
متن کاملOn the Nodal Count for Flat Tori
We give an explicit formula for the number of nodal domains of certain eigenfunctions on a flat torus. We apply this to an isospectral but not isometric family of pairs of flat four-dimensional tori constructed by Conway and Sloane, and we show that corresponding eigenfunctions have the same number of nodal domains. This disproves a conjecture by Brüning, Gnutzmann, and Smilansky.
