英文摘要
We studied geometric constants and norm inequalities in Banach spaces. In particular the relation between James and von Neumann-Jordan constants was discussed intensively, and we obtained a quite simple inequality about these two constants. This answers affirmatively a question posed by Alonso-Martin-Papini, and improves all previous results concerning these inequalities. We also investigated refined generalizations of norm inequalities.
