Links and analytic invariants of superisolated singularities
I. Luengo-Velasco, A. Melle-Hernandez, A. Nemethi
By using superisolated surface singularities whose link is a rational homology sphere we give counterexamples to some of the most important conjetures concernig invariants of norma…
Waiting for a bat to fly by (in polynomial time)
Itai Benjamini, Gady Kozma, Laszlo Lovasz +2
We observe returns of a simple random walk on a finite graph to a fixed node, and would like to infer properties of the graph, in particular properties of the spectrum of the trans…
An estimate about multiple stochastic integrals with respect to a normalized empirical measure
Peter Major
Let a sequence of iid. random variables be given on a measurable space with distribution together with a function on the product spa…
Mod 2 indecomposable orthogonal invariants
M. Domokos, P. E. Frenkel
Over an algebraically closed base field of characteristic 2, the ring of invariants is studied, being the orthogonal group O(n) or the special orthogonal group SO(n)…
Representation rings of quantum groups
M. Domokos, T. H. Lenagan
Generators and relations are given for the subalgebra of cocommutative elements in the quantized coordinate rings of the classical groups, where the deformation parameter q is tran…
Contact 3-manifolds with infinitely many Stein fillings
Burak Ozbagci, Andras I. Stipsicz
Infinitely many contact 3-manifolds each admitting infinitely many, pairwise non-diffeomorphic Stein fillings are constructed. We use Lefschetz fibrations in our constructions and…
Cut vertices in commutative graphs
James Conant, Ferenc Gerlits, Karen Vogtmann
The homology of Kontsevich's commutative graph complex parameterizes finite type invariants of odd dimensional manifolds. This {\it graph homology} is also the twisted homology of…
Seifert fibered contact three-manifolds via surgery
Paolo Lisca, Andras I. Stipsicz
Using contact surgery we define families of contact structures on certain Seifert fibered three-manifolds. We prove that all these contact structures are tight using contact Ozsath…
Sum-free sets in abelian groups
Ben Green, Imre Z. Ruzsa
Let A be a subset of an abelian group G. We say that A is sum-free if there do not exist x,y and z in A satisfying x + y = z. We determine, for any G, the cardinality of the larges…
Less than many translates of a compact nullset may cover the real line
Marton Elekes
We answer a question of Darji and Keleti by proving in that there exists a compact nullset $C_0\subset\RR$ such that for every perfect set $P\subset\RR$ there exists $x\in\RR…
Heegaard Floer Invariants and Tight Contact Three--Manifolds
P. Lisca, A. I. Stipsicz
Let Y(r) be the closed, oriented three-manifold obtained by performing rational r-surgery on the right-handed trefoil knot in the three-sphere. Using contact surgery and the Heegaa…
On the Hardy-Littlewood majorant problem
Ben Green, Imre Ruzsa
Consider a trigonometric polynomial f of degree N, and associate to it the polynomial F in which each coefficient of f is replaced by its absolute value. F is called the majorant o…
On orthogonal invariants in characteristic 2
M. Domokos, P. E. Frenkel
Working over an algebraically closed base field of characteristic 2, the ring of invariants is studied, where is the orthogonal group O(n) or the special orthogonal g…
Classification of 't Hooft instantons over multi-centered gravitational instantons
Gabor Etesi
This work presents a classification of all smooth 't Hooft-Jackiw-Nohl-Rebbi instantons over Gibbons-Hawking spaces. That is, we find all smooth SU(2) Yang-Mills instantons over th…
Total curvature and spiralling shortest paths
Imre Barany, Krystyna Kuperberg, Tudor Zamfirescu
This paper gives a partial confirmation of a conjecture of P. Agarwal, S. Har-Peled, M. Sharir, and K. Varadarajan that the total curvature of a shortest path on the boundary of a…
