摘要

We consider the problem of finding u ∈ L~2(I), I = (0,1)~2 is contained in R~2, satisfying ∫_I u(x,y)x~(α_l) dx dy = μ_(kl), where k, l = 0, 1, 2, …, (α_k) is a sequence of pairwise distinct real numbers which are greater than -1/2, and μ = (μ_(kl)) is a given bounded sequence of real numbers. This is an ill-posed problem. We shall regularize the problem by finite moments and then, apply the result to reconstruct a function from a sequence of its Laplace transforms.
