A remark on the slicing problem
The purpose of this article is to describe a reduction of the slicing problem to the study of the parameter I1(K,Z ◦ q (K)) = ∫ K ‖〈·, x〉‖Lq(K)dx. We show that an upper bound of the form I1(K,Z ◦ q (K)) 6 C1q snL2K , with 1/2 6 s 6 1, leads to the estimate Ln 6 C2 4 √ n logn q 1−s 2 , where Ln := max{LK : K is an isotropic convex body inR}.
متن کاملA remark on the second neighborhood problem
Seymour’s second neighborhood conjecture states that every simple digraph (without digons) has a vertex whose first out-neighborhood is at most as large as its second out-neighborhood. Such a vertex is said to have the second neighborhood property (SNP). We define ”good” digraphs and prove a statement that implies that every feed vertex of a tournament has the SNP. In the case of digraphs missi...
متن کاملA Remark on the Kramers Problem
1. Evolution of a physical system can be ordered in multi-timescales. Details of evolution on short-time-scale do not need for description in a closed form of a system evolution on long-time-scale and appears on this scale only in an average form. The prototype of such kind physical systems is dissipative Brownian motion of a particle in an external potential field. In this problem, with the ex...
متن کاملA remark on Giuga’s conjecture and Lehmer’s totient problem∗
Giuga has conjectured that if the sum of the (n− 1)-st powers of the residues modulo n is −1 (mod n), then n is 1 or prime. It is known that any counterexample is a Carmichael number. Lehmer has asked if φ(n) divides n−1, with φ being Euler’s function, must it be true that n is 1 or prime. No examples are known, but a composite number with this property must be a Carmichael number. We show that...
متن کاملon translation of politeness strategies in dialogues involving female characters in translations and retranslations of novels translated before and after the islamic revolution of iran and their effects on the image of women: a polysystem theory approach
abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
