Pointwise decay for semilinear wave equations on Kerr spacetimes

Research output: Contribution to journalArticlepeer-review


In this article, we prove pointwise bounds for solutions to the semilinear wave equation with integer powers p≥ 3 on Kerr backgrounds with small angular momentum and small initial data. We expect that the bounds proved in this paper are optimal.
