 We 
 show that if Y is the boundary of an almost-rational 
 plumbing, then the framed instanton 
 Floer homology of Y is isomorphic to its Heegaard 
 Floer homology. This class of 3-manifolds 
 includes all Seifert fibered rational homology 
 spheres. Our proof utilizes lattice homology, 
 and relies on a decomposition theorem 
 for instanton Floer cobordism maps established 
 by John Baldwin and Steven Sivek. This is 
 joint work with Antonio Alfieri, John Baldwin, 
 and Steven Sivek.\n\n
