Potential isomorphism and semi-proper trees
Alex Hellsten, Tapani Hyttinen, Saharon Shelah
We study a notion of potential isomorphism, where two structures are said to be potentially isomorphic if they are isomorphic in some generic extension that preserves stationary se…
Van der Waerden spaces and Hindman spaces are not the same
Menachem Kojman, Saharon Shelah
A Hausdorff topological space X is van der Waerden if for every sequence (x_n)_n in X there is a converging subsequence (x_n)_{n in A} where subset A of omega contains arithmetic p…
Characterizing automorphism groups of ordered abelian groups
Rüdiger Göbel, Saharon Shelah
We characterize the groups isomorphic to full automorphism groups of ordered abelian groups. The result will follow from classical theorems on ordered groups adding an argument fro…
Disorder and thermally driven vortex-lattice melting in La{2-x}Sr{x}CuO{4} crystals
Y. Radzyner, A. Shaulov, Y. Yeshurun +3
Magnetization measurements in La{2-x}Sr{x}CuO{4} crystals indicate vortex order-disorder transition manifested by a sharp kink in the second magnetization peak. The transition fiel…
Kulikov's problem on universal torsion-free abelian groups
Saharon Shelah, Lutz Strüngmann
Let T be an abelian group and lambda an uncountable regular cardinal. We consider the question of whether there is a lambda-universal group G^* among all torsion-free abelian group…
Total Photoabsorption Cross Sections of A=6 Nuclei with Complete Final State Interaction
Sonia Bacca, Mario Andrea Marchisio, Nir Barnea +2
The total photoabsorption cross sections of 6He and 6Li are calculated microscopically with full inclusion of the six-nucleon final state interaction using semirealistic nucleon-nu…
