Web24. nov 2024 · The space of long knots just removes some ambiguity. Remember that there is a fiber sequence $\text{Emb}_*(S^1, S^3) \to \text{Emb}(S^1, S^3) \to (TS^3 \setminus 0)$, the last map sending $\gamma$ to $\gamma'(0)$ and the first is the space of embeddings with prescribed values for $\gamma(0)$ and the derivative there. WebAbstract. We characterize the $ (1,1)$ knots in the 3-sphere and lens spaces that admit non-trivial L-space surgeries. As a corollary, 1-bridge braids in these manifolds admit non …

The connect sum of knots has a block diagonal presentation matrix for its Alexander module, hence the H1 is a direct sum. (Also, the rank of a finite abelian group is 0.
