摘      要:In this paper the author proves a new fundamental lemma of Hardy-Lebesgue class H2(σ) and by this lemma obtains some fundamental results of exponential stability of C0-semigroup of bounded linear operators in Banach spaces. Specially, if ωs=sup{Reλ; λ∈σ(A)}-1‖; Reλ≥σ}sup, 0) and A is the infinitesimal generator of a G0-semigroup etA in a Banach space X, then (a)integral from n=0 to ∞(e-σt|f(etAx)|f(etAx)|dt* and x∈X; (b) there exists M0 such that ‖etAx‖≤Neσt‖Ax‖, x∈D(A); (c) there exists a Banach space X such that ‖etAx‖≤eσt‖x‖, x∈X.
