我们构造了一个新的位于两条平行线之间的紧凸嵌入古解。利用这个解,我们对文[1]中的流的所有凸古解进行了分类。此外,我们还证明了中的任意非紧凸嵌入古解必是平移解。
We construct a new compact convex embedded ancient solution of theflow in,that lies between two parallel lines. Using this solution we classify all convex ancient solutions of theflow in, for. Moreover, we show that any non-compact convex embedded ancient solution of theflow in,must be a translating solution.
