Vaught’s conjecture on analytic sets
In each of these case the result was shortly or immediately after extended to analytic sets. For this purpose let us write TVC(G,Σ∼ 1 1) if whenever G acts continuously on a Polish space X and A ⊂ X is Σ∼ 1 1 (or analytic) then either |A/G| ≤ א0 or there is a perfect set of orbit inequivalent points in A. Thus we have TVC(G,Σ∼ 1 1) for each of the group in the class mentioned in 0.1-0.4 above. ...
متن کاملOn a conjecture about monomial Hénon mappings
A monomial Hénon mapping is defined as the wellknown two-dimensional Hénon map with the quadratic term replaced by a monomial. This paper introduces a conjecture about monomial Hénon mappings: Even Hénon mappings are chaotic and odd Hénon mappings are not chaotic in the first quadrant of the bifurcation parameter space. This conjecture is based on numerical simulations of this type of map.
متن کاملOn a conjecture about relative lengths
We need some definitions from [1]. Let C ⊂ R2 be a convex body. A chord pq of C is called an affine diameter of C, if there is no longer parallel chord in C. The ratio of |ab| to 1 2 |a′b′|, where a′b′ is an affine diameter of C parallel to ab, is called the C-length of ab, or the relative length of ab, if there is no doubt about C. We denote it by λC(ab). Denote by λn the relative length of a ...
متن کاملOn a coloring conjecture about unit fractions
We prove an old conjecture of Erdős and Graham on sums of unit fractions: There exists a constant b > 0 such that if we r-color the integers in [2, br ], then there exists a monochromatic set S such that ∑ n∈S 1/n = 1.
متن کاملOn a Conjecture about Binary Strings Distribution
It is a difficult challenge to find Boolean functions used in stream ciphers achieving all of the necessary criteria and the research of such functions has taken a significant delay with respect to cryptanalyses. A lot of attacks has led to design criteria for these functions; mainly: balancedness, a high algebraic degree, a high nonlinearity, a good behavior against Fast Algebraic Attacks and ...
