We analyze the effect of adding, removing, and moving basepoints on link Floer homology.
We prove that adding or removing basepoints via a procedure called quasistabilization is
a natural operation on a certain version of link Floer homology, which we call
. We
consider the effect on the full link Floer complex of moving basepoints, and develop a
simple calculus for moving basepoints on the link Floer complexes. We apply it
to compute the effect of several diffeomorphisms corresponding to moving
basepoints. Using these techniques we prove a conjecture of Sarkar about the
map on the full link Floer complex induced by a finger move along a link
component.
