We obtain an integro-differential evolution equation, which we solve by taking initial data on a null cone. As a corollary, we obtain elementary derivations of expected properties of linear waves in de Sitter spacetime: boundedness in terms of (characteristic) initial data, and a Price law establishing uniform exponential decay, in Bondi time, to a constant.<\/jats:p>","DOI":"10.1063\/1.4721644","type":"journal-article","created":{"date-parts":[[2012,5,26]],"date-time":"2012-05-26T22:05:10Z","timestamp":1338069910000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":8,"title":["Spherical linear waves in de Sitter spacetime"],"prefix":"10.1063","volume":"53","author":[{"given":"Jo\u00e3o L.","family":"Costa","sequence":"first","affiliation":[{"name":"Instituto Universit\u00e1rio de Lisboa (ISCTE-IUL) 1 , Lisboa, Portugal"},{"name":"Universidade T\u00e9cnica de Lisboa 3 Centro de An\u00e1lise Matem\u00e1tica, Geometria e Sistemas Din\u00e2micos, Instituto Superior T\u00e9cnico, , Lisboa, Portugal"}]},{"given":"Artur","family":"Alho","sequence":"additional","affiliation":[{"name":"Universidade do Minho 2 Centro de Matem\u00e1tica, , Gualtar, 4710-057 Braga, Portugal"}]},{"given":"Jos\u00e9","family":"Nat\u00e1rio","sequence":"additional","affiliation":[{"name":"Universidade T\u00e9cnica de Lisboa 3 Centro de An\u00e1lise Matem\u00e1tica, Geometria e Sistemas Din\u00e2micos, Instituto Superior T\u00e9cnico, , Lisboa, Portugal"}]}],"member":"317","published-online":{"date-parts":[[2012,5,25]]},"reference":[{"key":"2023062804031518100_c1","doi-asserted-by":"publisher","first-page":"697","DOI":"10.1007\/s00220-008-0553-y","article-title":"Decay and non-decay of the local energy for the wave equation on the de Sitter-Schwarzschild metric","volume":"282","year":"2008","journal-title":"Comm.
