Generic left-separated spaces and calibers

Istvan Juhász, Saharon Shelah

We use a natural forcing to construct a left-separated topology on an arbitrary cardinal kappa. The resulting left-separated space X_kappa is also 0-dimensional T_2, hereditarily L…

Weakly multiplicative coactions of quantized function algebras

M Domokos, T H Lenagan

A condition is identified which guarantees that the coinvariants of a coaction of a Hopf algebra on an algebra form a subalgebra, even though the coaction may fail to be an algebra…

An infinite family of tight, not semi-fillable contact three-manifolds

Paolo Lisca, Andras I Stipsicz

We prove that an infinite family of virtually overtwisted tight contact structures discovered by Honda on certain circle bundles over surfaces admit no symplectic semi-fillings. Th…

Orbits for the adjoint coaction on quantum matrices

M. Domokos, R. Fioresi, T. H. Lenagan

Conjugation coactions of the quantum general linear group on the algebra of quantum matrices have been introduced in an earlier paper and the coinvariants have been determined. In…

On Yang--Mills instantons over multi-centered gravitational instantons

Gabor Etesi, Tamas Hausel

In this paper we explicitly calculate the analogue of the 't Hooft SU(2) Yang--Mills instantons on Gibbons--Hawking multi-centered gravitational instantons which come in two parall…

Note on a reformulation of the strong cosmic censor conjceture based on computability

Gabor Etesi

In this letter we provide a reformulation of the strong cosmic censor conjecture taking into account recent results on Malament--Hogarth space-times. We claim that the strong versi…

Characterizing continuity by preserving compactness and connectedness

Janos Gerlits, Istvan Juhasz, Lajos Soukup +1

Let us call a function from a space into a space preserving if the image of every compact subspace of is compact in and the image of every connected subspace of…

On a problem of Turan about positive definite functions

Mihail N. Kolountzakis, Szilard Gy. Revesz

We study the following question posed by Turan. Suppose K is a convex body in Euclidean space which is symmetric with respect to the origin. Of all positive definite functions supp…
