Abstract. In this paper, essentially developing
the method of [1] (H. H. Bang and M. T. Thu, A Gagliardo-Niremberg
inequality for Orlicz spaces, East J. On Approximations 10
(2004) 371--377) and [10] (E. M. Stein, Functions of exponential type, Ann.
Math. 65 (1957) 582--592), we give an extension of the
Gagliardo-Nirenberg inequality to Lorentz spaces.
