Noether Symmetry in $f(T)$ Theory

摘要: Abstract As is well known, symmetry plays an important role in the theoretical physics. In particular, well-known Noether useful tool to select models motivated at a fundamental level, and find exact solution given Lagrangian. present work, we try consider f ( T ) theory. At first, briefly discuss Lagrangian formalism of point-like explicitly constructed. Based on this Lagrangian, explicit form theory corresponding are found by requiring symmetry. resulting = μ n theory, universe experiences power-law expansion t ∼ 2 / 3 . Furthermore, physical quantities solution, that if > our can be accelerated without invoking dark energy. Also, test with latest Union2 Type Ia Supernovae (SNIa) dataset which consists 557 SNIa, it consistent observational data fact.
