Finite subgraphs of uncountably chromatic graphs
Péter Komjáth, Saharon Shelah
It is consistent that for every monotonically increasing function f:omega->omega there is a graph with size and chromatic number aleph_1 in which every n-chromatic subgraph has at…
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…
A partition theorem for scattered order types
Peter Komjath, Saharon Shelah
If phi is a scattered order type, mu a cardinal, then there exists a scattered order type psi such that psi->[phi]^1_{mu,aleph_0} holds.
Clones from Creatures
Martin Goldstern, Saharon Shelah
A clone on a set X is a set of finitary operations on X which contains all the projections and is closed under composition. The set of all clones forms a complete lattice Cl(X) wit…
Some notes concerning the homogeneity of Boolean algebras and Boolean spaces
Stefan Geschke, Saharon Shelah
We consider homogeneity properties of Boolean algebras that have nonprincipal ultrafilters which are countably generated.It is shown that a Boolean algebra B is homogeneous if it i…
The Coulomb Blockade in Quantum Boxes
Eran Lebanon, Avraham Schiller, Frithjof B. Anders
The charging of a quantum box connected to a lead by a single-mode point contact is solved for arbitrary temperatures, tunneling amplitudes, and gate voltages, using a variant of W…
