Abstract
In this paper we will prove that if L is a continuous symmetric n-linear form on a Hilbert space and
bL
is the associated continuous n-homogeneous polynomial, then ǁLǁ = ǁbL
ǁ. For the proof we are
using a classical generalized inequality due to S. Bernstein for entire functions of exponential type.
Furthermore we study the case that if X is a Banach space then we have that
