环中的Hessel范数和圆盘平移
Hofer's norm and disk translations in an annulus
摘要：
设D是环A中的不可移动圆盘。设g是紧支撑Hamilton算子，它使D保持平移数n.我们证明了对于某个常数c，Hessel范数|g|由cn从下有界.我们还给出了这种哈密顿量的例子，它比D的明显旋转更有效。
英文摘要：
Let D be a non-displaceable disk in an annulus A. Suppose that g is a compactly supported Hamiltonian which preserves D with translation number n. We show that Hofer's norm |g| is bounded from below by cn for a certain constant c. We also give example of such Hamiltonian which is more efficient than the obvious rotation of D.
