This paper considers the cone multiplier operator which is defined byS μ f ^ ( ξ , τ ) = m μ ( ξ , τ ) f ^ ( ξ , τ ) , ( ξ , τ ) ∈ R 2 × Rwherem μ ( ξ , τ ) = φ ( τ )( 1 − | ξ | 2 / τ 2 ) + μ / Γ ( μ + 1 )and φ ∈ C 0 ∞ ( 1 , 2 ) . For −3/2 < μ < −3/14, sharp L p − L q estimates and endpoint estimates for S μ are obtained. 2000 Mathematics Subject Classification 42B15 (primary).
