Abstract

• Status of art on observational evidences.
• Cosmic acceleration and large scale structure motivates bot MOG and DS.
• How can we discriminate between Dark Side and MOG?
• There exists some observation/experiment capable of being addressed

   just in one way (MOG or DS)?

• Non-linear relativistic effects in structure formation needs to be

   understood: they may be relevant when extremely large scales scales are

considered in simulations, in view of next generation surveys

• Primordial GR effects on very large scales can be studied with non-linear

   perturbative methods and are relevant for measuring non-Gaussianity

and affect bias.

• Fully-non linear scales can be studied with post-Newtonian methods, and

   the goal is to implement these in simulations
