Let H and K be quasiconvex subgroups of a negatively curved locally extended Ž . residually finite LERF group G. It is shown that if H is malnormal in G, then the double coset KH is closed in the profinite topology of G. In particular, this is true if G is the fundamental group of an atoroidal LERF

## Abstract In this paper, we consider the asymptotic Dirichlet problem for the Schrödinger operator on a Cartan–Hadamard manifold with suitably pinched curvature. With potentials satisfying a certain decay rate condition, we give the solvability of the asymptotic Dirichlet problem for the Schrödin
Generalizing results of Lemmermeyer, we show that the 2-ranks of the Tate Shafarevich groups of quadratic twists of certain elliptic curves with a rational point of order 2 can be arbitrarily large. We use only quadratic residue symbols in a quadratic field to obtain our results.
Let \(X\) be a smooth proper connected algebraic curve defined over an algebraic number field \(K\). Let \(\pi_{1}(\bar{X})\), be the pro-l completion of the geometric fundamental group of \(\bar{X}=X \otimes_{k} \bar{K}\). Let \(p\) be a prime of \(K\), which is coprime to l. Assuming that \(X\) ha
A kind of novel structure polymer, a poly(phenylenevinylene) (PPV) derivative containing electron-transporting groups on the main chain (OPPV), was developed according to the polycondensation mechanism. The I-V characteristics at the low-voltage region with negative differential resistance were obse
