Query: New smooth counterexamples to the Hamiltonian Seifert conjecture   We construct a new aperiodic symplectic plug and hence new smooth
counterexamples to the Hamiltonian Seifert conjecture in R^{2n} for n>2. In
other words, we develop an alternative procedure, to those of V. L. Ginzburg
and M. Herman, for constructing smooth Hamiltonian flows, on the standard
symplectic R^{2n} for n>2, which have compact regular level sets that contain
no periodic orbits. The plug described here is a modification of those built by
Ginzburg. In particular, we utilize a different "trap" which makes the
necessary embeddings of this plug much easier to construct.
