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…
Tight, not semi--fillable contact circle bundles
Paolo Lisca, Andras I. Stipsicz
Extending our earlier results, we prove that certain tight contact structures on circle bundles over surfaces are not symplectically semi--fillable, thus confirming a conjecture of…
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…
Thermodynamic limit and proof of condensation for trapped bosons
Andras Suto
We study condensation of trapped bosons in the limit when the number of particles tends to infinity. For the noninteracting gas we prove that there is no phase transition in any di…
Randomized Approximation Schemes for Cuts and Flows in Capacitated Graphs
Andras Benczur, David R. Karger
We improve on random sampling techniques for approximately solving problems that involve cuts and flows in graphs. We give a near-linear-time construction that transforms any graph…
A divisorial valuation with irrational volume
Alex Kuronya
In this paper we present a divisorial valuation with irrational volume using an algebro-geometric construction.
