Some Formulae of n-Norms and Their Identicalness in a Hilbert Space

M. P. Singh, S. Romen Meitei
Abstract—In this paper, we discuss the concept of n-normed spaces and generalize a formulae of n-norm. Further we prove the equality of seven formulae of n-norms on a Hilbert space and eight formulae of n-norms on a separable Hilbert space. An alternative formula of n-norm on the dual of an n-normed space is introduced. Also, we show its equality with two alternative formulae.
