我们发现在所有维度的代数,但不是几何双切片的结。我们的新障碍涉及的卡森戈登不变量的有限循环覆盖在奇数维和无限循环覆盖在偶数维。这些相同的不变量为偶数维纽结的双射性和可逆性提供了新的判据。
We find knots in all dimensions which are algebraically but not geometri- cally doubly slice. Our new obstructions involve the Casson-Gordon invariants of the finite cyclic covers in odd dimensions and of the infinite cyclic cover in even dimensions. These same invariants provide new criteria for amphicheirality and invertibility of even-dimensional knots.
