WebbWe got a new pinching theorem (Theorem 6). The theorem uniﬁed and sharpened the previous pinching theorems, and may become the starting point of the gap theorem of Peng-Terng [15] type in high codimensions (see Conjecture 4). In the last part of this paper, we proved the conjecture of B¨ottcher and Wenzel [1].
