We … WebbWe wish to determine the simplicial homology groups. We have Δ 0 = v , Δ 1 = a, b, c and Δ 2 = f (of course, all brackets in this context mean the free abelian group on the enclosed generators). For δ 0, we have im δ 0 = { 0 } and ker δ 0 = Δ 0 . For δ 1, we have δ 1 ( a) = δ 1 ( b) = δ 1 ( c) = v − v = 0 .
