Let λ> 0 and△ λ:=− d 2 d x 2− 2 λ x d d x be the Bessel operator on R+:=(0,∞). The authors show that the oscillation operator O (P⁎[λ]) and variation operator V ρ (P⁎[λ]) of the Poisson semigroup {P t [λ]} t> 0 associated with Δ λ are both bounded on L p (R+, d m λ) for p∈(1,∞), BMO (R+, d m λ), from L 1 (R+, d m λ) to L 1,∞(R+, d m λ), and from H 1 (R+, d m λ) to L 1 (R+, d m λ), where ρ∈(2,∞) and d m λ (x):= x 2 λ d x. As an application, an equivalent characterization of H 1 (R+, d m λ) in terms of V ρ (P⁎[λ]) is also established. All these results hold if {P t [λ]} t> 0 is replaced by the heat semigroup {W t [λ]} t> 0.
