Spectral multiplier theorems via $$H^\infty $$ H ∞ calculus and R-bounds

Abstract: We prove spectral multiplier theorems for Hörmander classes H α p for 0-sectorial operators A on Banach spaces assuming a bounded H ∞ (Σ σ ) calculus for some σ ∈ (0, π) and norm and certain R-bounds on one of the following families of operators: the semigroup e −zA on C + , the wave operators e isA for s ∈ R, the resolvent (λ − A) −1 on C\R, the imaginary powers A it for t ∈ R or the Bochner-Riesz means (1 − A/u) α + for u > 0. In contrast to the existing literature we neither assume that A operates on an L p… Show more

“…This statement makes sense in an arbitrary Banach space X and a set τ ⊂ B(X) is called R-bounded if (1.2) holds for all S i ∈ τ and x i ∈ X. Using R-boundedness in place of kernel estimates and the holomorphic H ∞ (Σ σ ) calculus instead of the spectral theorem for selfadjoint operators, one can develop a theory of spectral multiplier theorems for 0-sectorial operators on Banach spaces (see [21,22,23,24,25]). Again, R-bounds for one of the operator families listed above are sufficient to secure H α 2 (R + ) spectral theorems for such operators A.…”
