Abstract
We show that $|MS(L_1 # L_2)|=|MS(L_1)|\times|MS(L_2)|\times\mathbb{R}$ when and are any non-split and non-fibred links. Here denotes the Kakimizu complex of a link , which records the taut Seifert surfaces for . We also show that the analogous result holds if we study incompressible Seifert surfaces instead of taut ones.
