We prove the Cauchy-Rassias stability of linear n-inner product preserving
mappings in n-inner product Banach spaces. We apply the Cauchy-Rassias
inequality that plays an influencial role in the subject of functional
equations. The inequality was introduced for the first time by Th.M.Rassias in
his paper entitled: On the stability of the linear mapping in Banach spaces,
Proc. Amer. Math.Soc. 72(1978), 297-300.Comment: 13 pages, Added references, and title and abstract change
