Iterative methods of solution for integral equations with convolution

In this paper we construct iterative methods for the solution of integral equations with convolution of the form (1)λx(t1,…,xl)  + ∫ab….. ∫ab h(t1−τ1,…,tl−τl)x(τ1,…,τl)dτ1…dτl= g(t1,…,tl)     (λ≥0).https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780367812027/499b2676-17a6-4805-9fd8-78c8baf0b813/content/eq152.tif"/>
