Dedicated to the memory of Professor Bo-Ying Wang

Huan-Nan Shia, Pei Wanga, Jian Zhang, Wei-Shih Du

Abstract：By transferring the judgment of convex functions of several variables into the judgment of convex functions of one variable, the authors discuss the convexity of some convex functions of several variables.

Keywords: convex function of several variables, convex function of one variable, judgment criteria
