Covariant formulation of f(Q) theory

Abstract: In Symmetric Teleparallel General Relativity, gravity is attributed to the non-metricity. The so-called “coincident gauge” is usually taken in this theory so that the affine connection vanishes and the metric is the only fundamental variable. This gauge choice was kept in many studies on the extensions of Symmetric Teleparallel General Relativity, such as the so-called f(Q) theory. In this paper, we point out that sometimes this gauge choice conflicts with the coordinate system we selected based on symmetry. T… Show more

“…However, special care is needed when the equations of motion are considered after a partial gauge fixing at the level of the metric. For example, when we take a FLRW space-time or a static and spherically symmetric manifold, there is the possibility that the gauge in which Γ λ µν = 0 is realised is incompatible with the coordinate system in which the metric is expressed and this may lead to unnecessary restrictions in the equations of motion [23,34].…”

“…20 Zwitterionic polymers bear both cationic and anionic groups have been proved effective in modifying membrane with improved permeability and antifouling performance. [21][22][23] And zwitterionic polymer brushes effectively shield surface carboxyl groups, providing steric hindrance and preventing dirt adsorption. 24 As modification with zwitterionic materials to improve anti-fouling performance of RO membranes has been widely reported, [25][26][27] modifying FO membrane to achieve better fouling resistance should be practical and feasible.…”
