Polyak-Viro type formula for the Milnor triple linking number of link diagrams with multiple-crossings
Yusaku Okuhara, Keiichi Sakai
We obtain Polyak-Viro type formula for the Milnor triple linking number that can be applied to diagrams with triple or more multiple-crossings. The proof is based on the idea of Br…
