For every genus $g \geqslant 2$, we construct an infinite family of strongly quasipositive fibred knots $K_n$ having the same Seifert form as the torus knot $T(2, 2g + 1)$. In particular, their homological monodromies agree and their signatures and four-genera are maximal: $\lvert \sigma (K_n) \rvert = 2g_4 (K_n) = 2g$. On the other hand, the geometric stretching factors are pairwise distinct and the knots are pairwise not ribbon concordant.

关于具有相同塞弗特形式的纤维结族

对于每个属$ g \ geqslant 2 $，我们构建一个无限准族的强拟正纤维结$ K_n $，其塞弗特形式与环结$ T（2，2g + 1）$相同。特别地，它们的同源性一元性一致，并且它们的签名和四属最大：$ \ lvert \ sigma（K_n）\ rvert = 2g_4（K_n）= 2g $。另一方面，几何拉伸因子是成对的，结是成对的而不是色带一致的。
