چکیده
We discuss Q-balls in the complex signum-Gordon model in d-dimensional space for d = 1, 2, 3. The Q-balls have strictly finite size. Their total energy is a power-like function of the conserved U (1) charge with the exponent equal to (d + 2)(d + 3) −1. In the cases d = 1 and d = 3 explicit analytic solutions are presented.

We give a simple geometric explanation for the similarity transformation mapping one-dimensional conformal mechanics to free-particle system. Namely, we show that this transformation corresponds to the inversion of the Klein model of Lobachevsky space (non-compact complex projective plane) fI CP 1 . We also extend this picture to the N = 2k superconformal mechanics described in terms of Lobache...

Using the WKBJ approximation we obtain numerical plots of the power emission spectrum for the evaporation of massless bulk Dirac fermions from six dimensional black holes off a tense 3-brane with codimension two. We also present the multiplicity factors for eigenvalues of the deficit four sphere and show that these reduce to the usual case in the tenseless limit.

A formulation of U(1) symmetric classical membrane motions (preserving one rotational symmetry) is given, and reductions to systems of ODE’s, as well as some ideas concerning singularities and integrability. Let me start by giving some particular example(s) of a 2-dimensonal (timelike, time periodic) extremal manifold M2 ⊂ R and 3-folds (singularities included) of vanishing mean curvature, in 4...

The role of Chern-Simons (CS) actions is reviewed, starting from the observation that all classical actions in Hamiltonian form can be viewed as 0+1 CS systems, in the same class with the coupling between the electromagnetic field and a point charge. Some suggestions are derived that could shed some light on the quantization problem in D=2n-1¿3 dimensions.
