Knot Floer homology of satellite knots with (1, 1) patterns.

For pattern knots admitting genus-one doubly pointed bordered Heegaard diagrams, we give an immersed-curve approach to compute the knot Floer chain complexes of the corresponding satellite knots. In particular, this approach provides a convenient way to compute the knot concordance invariant τ . For patterns P obtained from two-bridge links b(p, q), we derive a formula for the τ -invariant of P (T 2 , 3) and P (- T 2 , 3) in terms of (p, q). We use this formula to study whether such patterns induce homomorphisms on the knot concordance group, providing a glimpse at a conjecture due to Hedden. [ABSTRACT FROM AUTHOR]
