The above are notes based on lectures given at the Second TRR33 Winter School on cosmology, Passo del Tonale (Italy), December 2008.

 

I have not read them very carefully, but they represent a modern and accessible introduction to cosmic inflation.

 

To date, a hot big bang + inflation model has survived against its competitors as a good model of the early universe. It makes predictions of the fluctuations in the CMBR via quantum perturbation in the inflaton field. Observations seem to agree with this theoretical set-up.

 

It is expected that future more detailed studies of the CMBR may be able to differentiate between the many realisations of cosmic inflation.

 

Hope you all enjoy this account.
