In the real case the proof is based on properties of the action of the group of interval exchange transformations on the set of all monic polynomials of some given degree.. Finally

Notice also that, from this point of view, the condition of existence of rational periodic orbits is equivalent to the condition that Q is in the torsion of the group given by

In this paper, we generalize the result of Swan for a finite group to a p- periodic group F of finite ved which has a finite quotient whose a p-Sylow subgroup is elementary abelian

This phenomenon applies to expressions: cool (no. The difference separating frequency rates in the American survey group from the group of other nationalities is more

We propose that dark matter is stable as a consequence of an accidental Z 2 that results from a flavour symmetry group which is the double-cover group of the symmetry group of one

The paper is organized as follows: Section 2 gives preliminaries and general facts needed in the rest of the paper; Section 3 gives some background on the isometry group of a

In addition to two learning modes that are articulated in the literature (learning through incident handling practices, and post-incident reflection), the chapter

The zero-energy pinning mechanism described in this work is generic, and is the result of the electrostatic energy cost from the interaction of the finite charge Q M added to
