摘要

摘要

En 中文
In the present paper we consider the problem of numerical analytic continuation for an analytic function f(z) - f(x + iy) on a strip domain Omega(+) - {z -x + iy epsilon C vertical bar x epsilon R, 0 < y < y(0)}. The key difference with the known methods is that a novel iteration regularization method with a priori and a posteriori parameter choice rule is presented. The comparison in numerical aspect with other methods is also discussed. (C) 2014 Elsevier Inc. All rights reserved.
