摘要 |
In this talk, I will first review the standard dS/CFT correspondence.
Afterwards, I will introduce the inflation/deformed CFT correspondence. Two
examples— k inflation and slow roll inflation are studied using two different
methods— Witten diagram and conformal partial wave expansion. Witten diagram
can recover the full inflationary power spectrum and bispectrum while conformal
partial wave expansion can help us understand more about the relation with pure
CFT. A brief summary will be given in the end. |
