膜模型的k-稳定化

k-stabilization in brane models

M. Olechowski

摘要:

在具有高阶标量动力学项的5维模型中分析了膜间距的稳定性。运动方程和边界条件的背景和标量扰动。充分条件和(有一个例外)的稳定性的必要推导和讨论。结果表明,即使没有标量势和宇宙学常数,也有可能构造出稳定的膜组态。作为一个副产品,我们确定了一个大类的非标准边界条件的斯特姆-刘维尔算子是厄米。

英文摘要:

Stabilization of inter-brane distance is analyzed in 5-dimensional models with higher-order scalar kinetic terms. Equations of motion and boundary conditions for background and for scalar perturbations are presented. Conditions sufficient and (with one exception) necessary for stability are derived and discussed. It is shown that it is possible to construct stable brane configurations even without scalar potentials and cosmological constants. As a byproduct we identify a large class of non-standard boundary conditions for which the Sturm-Liouville operator is hermitian.
