It is well known that in the weak coupling regime, quantum field theories in
de Sitter space do not have a unique vacuum, but a class of vacua parametrized
by a complex parameter α, i.e., the so-called α-vacua. In this
article, using gauge/gravity duality, we calculate the symmetric two-point
function of strongly coupled N=4 supersymmetric Yang-Mills theory on
dS3. We find that there is a class of de Sitter invariant vacua,
parametrized by a set of complex parameters {αν}.Comment: 17 pages in JHEP style, references adde
