The Bach tensor is classically defined in dimension 4, and work from J. Bergman \citebergman:2004 and others shows that B = (1)/(2)U + (1)/(6)V where U and V are more basic 2-tensors, which are symmetric, divergence-free, algebraically independent, and quadratic in the Riemann tensor. In this paper, we extend H.-D. Cao and Q. Chen's results \citecaochen:2013 for Bach-flat gradient shrinking Ricci solitons to solitons with \mathfrakB = αU + βV = 0.
