Abstract
In 1967 Gurarii introduces a modulus of convexity beta Evarepsilon In this paper some properties of this modulus are analyzed They have their analogous on the well known Clarksons modulus of convexity delta Evarepsilon In particular we show that beta Evarepsilon can be defined in several equivalent forms We also prove that in lp spaces with 2 p the Gurariis modulus satifies the equality beta l pvarepsilon=1root p of1leftvarepsilon over 2 rightp for 0le varepsilon le 2
