摘要:

在德西特时空中的双粒子模型中,构建了具有时间非对称延迟-提前相互作用的模型。特别考虑了场型电磁相互作用和标量相互作用的特例。提出了在拉格朗日和哈密顿形式化中带有约束的显式协变描述。证明了这些模型在德西特不变性和可积性方面具有特性。通过投影算子技术,推导出运动方程的显式解。

英文摘要:

The two-particle models in de Sitter space-time with time-asymmetric retarded-advanced interactions are constructed. Particular cases of the field-type electromagnetic and scalar interactions are considered. The manifestly covariant descriptions of the models within the Lagrangian and Hamiltonian formalisms with constraints are proposed. It is shown that the models are de Sitter-invariant and integrable. An explicit solution of equations of motion is derived in quadratures by means of projection operator technique.
