Idempotent Ultrafilters and Polynomial Recurrence
In the thirty or so years since H. Furstenberg reproved Szemerédi’s theorem using methods from ergodic theory, many striking discoveries have been made in the area now known as Ergodic Ramsey theory. Perhaps the most surprising of these is the discovery that recurrence results can be obtained for polynomial sets, meaning sets of values of polynomials. The following pretty theorem, a special cas...
متن کاملIdempotent Ultrafilters, Multiple Weak Mixing and Szemerédi’s Theorem for Generalized Polynomials
It is possible to formulate the polynomial Szemerédi theorem as follows: Let qi(x) ∈ Q[x] with qi(Z) ⊂ Z, 1 ≤ i ≤ k. If E ⊂ N has positive upper density then there are a, n ∈ N such that {a, a+q1(n)−q1(0), a+qk(n)−qk(0)} ⊂ E. Using methods of abstract ergodic theory, topological algebra in βN, and some recently-obtained knowledge concerning the relationship between translations on nilmanifolds ...
متن کاملModels of Pa: Standard Sytems without Minimal Ultrafilters Sh944
We prove that N has an uncountable elementary extension N such that there is no ultrafilter on the Boolean Algebra of subsets of N represented in N which is minimal (i.e. Ramsey for partitions represented in N).
متن کاملPseudorandom Generators without the XOR Lemma
Impagliazzo andWigderson IW have recently shown that if there exists a decision problem solvable in time O n and having circuit complexity n for all but nitely many n then P BPP This result is a culmination of a series of works showing connections between the existence of hard predicates and the existence of good pseudorandom generators The construction of Impagliazzo andWigderson goes through ...
متن کاملLinear Ultrafilters
Let X be a k-vector space, and U a maximal proper filter of subspaces of X. Then the ring of endomorphisms of X that are ‘‘continuous’’ with respect to U modulo the ideal of those that are ‘‘trivial’’ with respect to U forms a division ring E(U ). (These division rings can also be described as the endomorphism rings of the simple left End( X )-modules.) We study this and the dual construction, ...
