Abstract
The purpose of the paper is to study the behavior at infinity of Fourier-Laplace transforms of distributions or more generally plurisubharmonic functions u in Cn with bounds of the form
The set L∞(u) of limits of Ttu = u(t·)/t as t → +∞ is a compact T invariant subset of the set PH of plurisubharmonic functions in Cn with v(ξ) ≤H(Im ξ), ξ ∈ Cn, and equality on CRn. Here H is a supporting function associated with u, and T is chain recurrent on L∞(u). The behavior of functions in PH at CRn is studied in detail, which leads to conditions on a set M ⊂PH which guarantee that M = L∞(u) for some u as above. One can then choose u = log ¦ F ¦ where F is the Fourier-Laplace transform of a distribution with compact support.
