Large sets without Fourier restriction theorems

چکیده
We construct a function that lies inLp(Rd)L^p(\mathbb {R}^d)for everyp?(1,?]p \in (1,\infty ]and whose Fourier transform has no Lebesgue points in Cantor set of full Hausdorff dimension. apply Kova?’s maximal restriction principle to show the same full-dimensional is avoided by any Borel measure satisfying nontrivial theorem. As consequence near-optimal fractal theorem ?aba and Wang, we hence prove there are previously unknown relations between dimension range possible exponents for measures supported set.

Planar digraphs without large acyclic sets
Given a directed graph, an acyclic set is a set of vertices inducing a directed subgraph with no directed cycle. In this note we show that for all integers n ≥ g ≥ 3, there exist oriented planar graphs of order n and digirth g for which the size of the maximum acyclic set is at most dn(g−2)+1 g−1 e. When g = 3 this result disproves a conjecture of Harutyunyan and shows that a question of Albert...
متن کاملRestriction Theorems for Homogeneous Bundles
We prove that for an irreducible representation τ : GL(n) → GL(W ), the associated homogeneousP k -vector bundle Wτ is strongly semistable when restricted to any smooth quadric or to any smooth cubic in P k , where k is an algebraically closed field of characteristic 6= 2, 3 respectively. In particular Wτ is semistable when restricted to general hypersurfaces of degree ≥ 2 and is strongly semis...
متن کاملNonrenormalization Theorems without Supersymmetry.
We derive a new class of one-loop nonrenormalization theorems that strongly constrain the running of higher dimension operators in a general four-dimensional quantum field theory. Our logic follows from unitarity: cuts of one-loop amplitudes are products of tree amplitudes, so if the latter vanish then so too will the associated divergences. Finiteness is then ensured by simple selection rules ...
متن کاملTauberian theorems for sum sets
Introduction. The sums formed from the set of non-negative powers of 2 are just the non-negative integers. It is easy to obtain “abelian” results to the effect that if a set is distributed like the powers of 2, then the sum set will be distributed like Dhe non-negative integers. We will be concerned here with converse, or “Tauberian” results. The main theme of this paper is t’he following quest...
متن کاملLarge-volume open sets in normed spaces without integral distances
We study open sets P in normed spaces X attaining a large volume while avoiding pairs of points at integral distance. The proposed task is to find sharp inequalities for the maximum possible d-dimensional volume. This problem can be viewed as an opposite to known problems on point sets with pairwise integral or rational distances.
