论文摘要
简明地描述了非典型时空体积形式的形式主义的基本特征及其在改良的重力理论和宇宙学中的应用。众所周知的单型重力理论似乎是一种非常特殊的情况。关于宇宙学目前面临的热门问题,我们特别简要概述了:(a)将暗能和暗物质作为单个物质实体的表现的统一描述 - 特殊的标量“ Darkon”; (b)具有重力的宇宙进化的典型模型 - “ fortaton”辅助动力学Higgs机制 - 动态抑制/生成自发的电气仪表对称对称性在“早期”/“晚”宇宙中破裂; (c)统一暗能量和暗物质与它们之间的扩散相互作用; (d)抑制第5次力量而无需微调的机制。
A concise description is presented of the basic features of the formalism of non-canonical spacetime volume-forms and its application in modified gravity theories and cosmology. The well known unimodular gravity theory appears as a very special case. Concerning the hot issues facing cosmology now, we specifically briefly outline the construction of: (a) unified description of dark energy and dark matter as manifestations of a single material entity -- a special scalar field "darkon"; (b) quintessential models of universe evolution with a gravity-"inflaton"-assisted dynamical Higgs mechanism -- dynamical suppression/generation of spontaneous electroweak gauge symmetry breaking in the "early"/"late" universe; (c) unification of dark energy and dark matter with diffusive interaction among them; (d) mechanism for suppression of 5-th force without fine-tuning.
