We prove a multiplier theorem for the Hermite-Triebel-Lizorkin spaces
introduced by Epperson in [Studia Math. 114 (1995), 87-103]. This exte
nds Thangavelu's theorem [Revist. Mat. Ibero 3 (1987), 1-24; Math. Not
es, vol. 42, 1993] on Hermite multipliers for L(p) spaces. We also pro
ve an L(p) boundedness result for a class of Hermite pseudo-multiplier
