Knot primality: knot Floer homology, metacyclic representations and twisted homology
Samantha Allen, Charles Livingston
We develop purely algebraic methods for proving that a knot is prime. Our approach uses the Heegaard Floer polynomial in conjunction with classical knot-theoretic methods: cyclic,…

Using knot Floer invariants to detect prime knots
Samantha Allen, Charles Livingston, Misha Temkin +1
We present knot primality tests that are built from knot Floer homology. The most basic of these is a simply stated and elementary consequence of Heegaard Floer theory: if the two-…
