“…exact solution, approximate solution, and absolute errors for bivariate type II fuzzy fredholm integral equations using homotopy perturbation method. Comparison between APxSn ∪ APxSn [10] (s, t, r), ∪ APxSn [10] (s, t, r) and exact solution ∪(ω 1 , ω 2 , r), ∪(ω 1 , ω 2 , r) used by HPM by metric D(∪, ∪) using the Definition 2.3 for Examples 6.1, where maxD ∪ APxSn [10] (s, t, r), ∪(ω 1 , ω 2 , r) = 3.7 × 10 -11 , and maxD ∪ APxSn [10] (s, t, r), ∪(ω 1 , ω 2 , r) = 1.0 × 10 -10 .…”
