【 摘 要 】

In this note, motivated by the question 1 in (Aron and Lohman, Pacific J. Math. 127 (1987), 209–231), we obtain an explicit formula for the -function in the real space . From this we see that the -function is continuous and attained at each point of the unit ball of , the space of real-valued continuous 2-homogeneous polynomials on .
