Filtered Instantons and the Concordance of Satellites

In \cite{NST23}, Nozaki-Sato-Taniguchi defined a family of invariants $r_s$ for integer homology spheres with filtered instanton homology \cite{FS92}. Coupling these with techniques in classical knot theory, we produce some results in the knot concordance group, including criteria for a family of satellite knots to be linearly independent and the independence of what we call the Whitehead $n$-ble $P_n$.
