An Iterative Tikhonov Regularization for Solving Singularly Perturbed Elliptic PDE

A variant of Tikhonov regularization for parabolic PDE with space derivative multiplied by a small parameter∊

“…However, we are dealing with unbounded operators for singularly perturbed problems. Hence, a special treatment is mandatory to address this problem as regularization theory for unbounded operators had received only very little attention in literature except for a few like [5,10,11] and reference therein.…”
