论文摘要
对称触发性重力是用非零的非赞誉张量构建的，而扭转和曲率都消失了。在此框架中，我们在标量调整理论中找到了确切的标量对称静态解，该理论在非MUTHRICITY标量和标量场之间建立了非微小耦合。事实证明，Bocharova-Bronnikov-Melnikov-Bekenstein解决方案具有对称触发平行的类似物（除了最近发现的公制触发平行的类似物外），而这些解决方案中的其他一些解决方案描述了标量的黑洞构型，在Riemannian或Metric Teleparallel scalparallaleal Calelarelaleal scalar-carrallaleal-Scalar-carrallallal scalar-cansor案例中未知。为了帮助分析，我们还为该理论得出了无发品定理。 Since the symmetric teleparallel scalar-tensor models also include $f(Q)$ gravity, we shortly discuss this case and further prove a theorem which says that by imposing that the metric functions are the reciprocal of each other ($g_{rr}=1/g_{tt}$), the $f(Q)$ gravity theory reduces to the symmetric teleparallel equivalent of general relativity (plus a宇宙常数），公制采用（反）de-sitter-schwarzschild形式。
Symmetric teleparallel gravity is constructed with a nonzero nonmetricity tensor while both torsion and curvature are vanishing. In this framework, we find exact scalarised spherically symmetric static solutions in scalar-tensor theories built with a nonminimal coupling between the nonmetricity scalar and a scalar field. It turns out that the Bocharova-Bronnikov-Melnikov-Bekenstein solution has a symmetric teleparallel analogue (in addition to the recently found metric teleparallel analogue), while some other of these solutions describe scalarised black hole configurations that are not known in the Riemannian or metric teleparallel scalar-tensor case. To aid the analysis we also derive no-hair theorems for the theory. Since the symmetric teleparallel scalar-tensor models also include $f(Q)$ gravity, we shortly discuss this case and further prove a theorem which says that by imposing that the metric functions are the reciprocal of each other ($g_{rr}=1/g_{tt}$), the $f(Q)$ gravity theory reduces to the symmetric teleparallel equivalent of general relativity (plus a cosmological constant), and the metric takes the (Anti)de-Sitter-Schwarzschild form.
