We study the equivariant genera of strongly invertible and periodic knots. Our techniques include some new strongly invertible concordance group invariants, Donaldson's theorem, and the g-signature. We find many new examples where the equivariant 4-genus is larger than the 4-genus.

强可逆和周期性结的等变 4-属

我们研究了强可逆和周期性结的等变属。我们的技术包括一些新的强可逆一致性群不变量、唐纳森定理和 g 签名。我们发现了许多新的例子，其中等变 4-genus 大于 4-genus。
