We will discuss a novel framework for studying how such induced doubling can be inherited from a more general class of multi-dimen sional subsets. It turns out that subsets of so-called quasi-cubes induce large doubling no matter the dimension of the ambient set. Time permitting \, we will discuss how it allows to deduce a structural theorem for sets w ith polynomially large additive doubling and an application to the ”few products\, many sums” problem of Bourgain and Chang.\nThis is joint work with I.Ruzsa\, D. Matlosci\, G. Shakan and D.

To do so\, we build on a quasirand omness and induction framework for Ramsey numbers introduced by Thomason a nd extended by Conlon\, demonstrating optimal ``effective quasirandomness' ' results about convergence of graphs. This optimality represents a natura l barrier to improvement.\n LOCATION:https://researchseminars.org/talk/WAC/2/ END:VEVENT BEGIN:VEVENT SUMMARY:Jozsef Solymosi (UBC) DTSTART:20200601T160000Z DTEND:20200601T170000Z DTSTAMP:20260422T225759Z UID:WAC/3 DESCRIPTION:Title: Sums and products along edges of sparse graphs\nby Jozsef Solymosi (UBC) a s part of Webinar in Additive Combinatorics\n\n\nAbstract\nIn their semina l paper Erdős and Szemerédi formulated conjectures on the size of sum se t and product set of integers. The strongest form of their conjecture is a bout sums and products along the edges of a graph\, when we consider sums and products of some pairs only. With Noga Alon and Imre Ruzsa we showed t hat this strong form of the Erdős-Szemerédi conjecture does not hold. In this talk I will list some related problems and recent results.\n LOCATION:https://researchseminars.org/talk/WAC/3/ END:VEVENT BEGIN:VEVENT SUMMARY:Dimitris Koukoulopoulos (Montreal) DTSTART:20200608T160000Z DTEND:20200608T170000Z DTSTAMP:20260422T225759Z UID:WAC/4 DESCRIPTION:Title: Galo is groups of polynomials of large degree\nby Dimitris Koukoulopoulos ( Montreal) as part of Webinar in Additive Combinatorics\n\n\nAbstract\nAbst ract: Let $\\mathcal{N}$ be a set of natural numbers and let us consider a ll monic polynomials of degree $n$ whose coefficients are in $\\mathcal{N} $. What are the odds that a polynomial chosen uniformly at random from thi s set is irreducible? Moreover\, what can we say about the distribution of its Galois group? I will present some recent results\, joint with Lior Ba ry-Soroker and Gady Kozma\, that show that if $\\mathcal{N}$ is not too sp arse\, then such random polynomials are highly likely to be irreducible an d have very large Galois group. The proofs uses a fun mixture of ideas fro m sieve methods\, the arithmetic of polynomials over finite fields\, prime s with restricted digits\, Galois theory and group theory.\n LOCATION:https://researchseminars.org/talk/WAC/4/ END:VEVENT BEGIN:VEVENT SUMMARY:Marina Iliopoulou (Kent) DTSTART:20200622T160000Z DTEND:20200622T170000Z DTSTAMP:20260422T225759Z UID:WAC/6 DESCRIPTION:Title: TBA< /a>\nby Marina Iliopoulou (Kent) as part of Webinar in Additive Combinator ics\n\nAbstract: TBA\n LOCATION:https://researchseminars.org/talk/WAC/6/ END:VEVENT BEGIN:VEVENT SUMMARY:Zachary Chase (Oxford) DTSTART:20200629T160000Z DTEND:20200629T170000Z DTSTAMP:20260422T225759Z UID:WAC/7 DESCRIPTION:Title: A ra ndom analogue of Gilbreath's conjecture\nby Zachary Chase (Oxford) as part of Webinar in Additive Combinatorics\n\n\nAbstract\nGiven a sequence a1\, a2\, ... of integers\, one can form the sequence |a1-a2|\, |a2-a3|\, .... Gilbreath's conjecture is that if you start with the sequence of the primes and iterate this consecutive differencing procedure\, then the firs t term of every sequence (besides the initial one) is a 1.

A conjecture of Chowla states that the values of the Liouville funct ion fluctuate between plus and minus in such a random way\, that all sign patterns of a given length appear with the same frequency. The Chowla conj ecture remains largely open and in this talk we will see how ergodic theor y combined with some feedback from number theory allows us to establish tw o variants of this conjecture. Key to our approach is an in-depth study of measure preserving systems that are naturally associated with the Liouvil le function. The talk is based on joint work with Bernard Host.\n LOCATION:https://researchseminars.org/talk/WAC/13/ END:VEVENT BEGIN:VEVENT SUMMARY:Thomas Bloom (Cambridge) DTSTART:20200710T160000Z

Additive Combinatorics\n\n\nAbstract\nWe prove that th e size of the product set of any finite arithmetic progression A in intege rs of size N is at least N^{2}/(log N)^{c+o(1)}\, where c=1-(1+loglog 2)/( log 2). This matches the bound in the celebrated Erdos multiplication tab le problem\, up to a factor of (log N)^{o(1)} and thus confirms a conjectu re of Elekes and Ruzsa.\nIf instead A is relaxed to be a subset of a finit e arithmetic progression in integers with positive constant density\, we p rove that the size of the product set is at least N^{2}/(log N)^{2log2-1 + o(1)}. This solves the typical case of another conjecture of Elekes and R uzsa on the size of the product set of a set A whose sum set is of size O (|A|).This is joint work with Yunkun Zhou.\n LOCATION:https://researchseminars.org/talk/WAC/59/ END:VEVENT BEGIN:VEVENT SUMMARY:Matthew Tointon (Bristol) DTSTART:20220302T150000Z DTEND:20220302T160000Z DTSTAMP:20260422T225759Z UID:WAC/60 DESCRIPTION:Title: Per colation on finite transitive graphs\nby Matthew Tointon (Bristol) as part of Webinar in Additive Combinatorics\n\nAbstract: TBA\n LOCATION:https://researchseminars.org/talk/WAC/60/ END:VEVENT BEGIN:VEVENT SUMMARY:Theresa Anderson (Purdue) DTSTART:20220316T150000Z DTEND:20220316T160000Z DTSTAMP:20260422T225759Z UID:WAC/61 DESCRIPTION:Title: Two meetings of number theory and analysis\nby Theresa Anderson (Purdue) as part of Webinar in Additive Combinatorics\n\nAbstract: TBA\n LOCATION:https://researchseminars.org/talk/WAC/61/ END:VEVENT BEGIN:VEVENT SUMMARY:Izabella Laba (University of British Columbia) DTSTART:20220330T140000Z DTEND:20220330T150000Z DTSTAMP:20260422T225759Z UID:WAC/62 DESCRIPTION:Title: Cyc lotomic divisibility: from integer tilings to harmonic analysis and geome tric measure theory\nby Izabella Laba (University of British Columbia) as part of Webinar in Additive Combinatorics\n\nAbstract: TBA\n LOCATION:https://researchseminars.org/talk/WAC/62/ END:VEVENT END:VCALENDAR
