Abstract

We show that large fragments of MM, e. g. the tree property and stationary reflection, are preserved by strongly (ω~1~ + 1)‐game‐closed forcings. PFA can be destroyed by a strongly (ω~1~ + 1)‐game‐closed forcing but not by an ω~2~‐closed. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

We extend the classical Ambarzumyan's theorem for the Sturm-Liouville equation (which is concerned only with Neumann boundary conditions) to the general boundary conditions, by imposing an additional condition on the potential function. Our result supplements the Pöschel-Trubowitz inverse spectral t

Let k be a finite extension of Q and p a prime number. Let K be a Z p -extension of k and S the set of all prime ideals in k which are ramified in K. We denote by A$ the p-Sylow subgroup of the S-divisor class group of K. We give a criterion for A$ =0 which can be applied for general Z p -extensions
