The exact values of nonsquare constants for a class of Orlicz spaces

Abstract

We extend the \(M_{\triangle}\)-condition from [Han J.,Li X.: On Exact Value of Packing for a Class of Orlicz Spaces. (Chinese), Journal of Tongji Univ. 30 (2002) 7, 895–899] and introduce the \(\Phi_{\triangle}\)-condition at zero. Next we discuss nonsquare constant in Orlicz spaces generated by an \(N\)-function \(\Phi(u)\) which satisfy \(\Phi_{\triangle}\)-condition. We obtain exact value of nonsquare constant in this class of Orlicz spaces equipped with the Luxemburg norm.
