2. Outline MOND TeVeS Test: CMB Test: strong lensing probability
Discussion

3. MOND

5. Interpolation function
With for x<<1 and for x>>1.
Generally, we can define (Zhao & Tian 2006)
So that for n=1.5 and standard form
for n=3

6. Then the “true” acceleration is

7. TeVeS (Tensor-Vector-Scalar)
The metric between TeVeS and General Relativity (GR) is
TeVeS cosmology has the same form with the LCDM

8. Test: CMB
