Abstract

In the setting of the massive Klein-Gordon equation on de Sitter space, we\ndiscuss Vasy's asymptotic data at conformal infinity in terms of plane waves.\nIn particular, we derive a short-hand formula for reconstructing solutions from\ntheir asymptotic data. Furthermore, we show that the natural Hadamard state\ninduced from future (or past) conformal infinity coincides with the\nBunch-Davies state.\n
