An a posteriori parameter choice strategy is proposed for the simplified regularization of ill-posed problems where no information about the smoothness of the unknown solution is required. If the smoothness of the solution ...

A class of discrepancy principles for the choice of parameters for the simplified regularization of ill-posed problems is proposed. This procedure does not require knowledge of the unknown solution, and if the smoothness ...

Chatelin has established, under assumptions on the unknown invariant subspace, the quadratic convergence of Newton's iterative refinements. We modify the procedure in line with Demmel's suggestions and obtain a criterion ...

The author would like to correct an error in the statement of a result 'in Bull. Aust. Math. Soc. 36 (1987) 485–492' and also to incorporate an additional result.

We present several basic results on ecg and use this parameter to prove that any connected graph G can be embedded as an induced subgraph of a graceful graph and as an induced subgraph of an eulerian graceful graph.

Schock(1984) considered a general a posteriori parameter choice strategy for the regularization of ill-posed problems which provide nearly the optimal rate of convergence. We improve the result of Schock and give a class ...

In this research paper, we obtain the equivalent symmetries of non-homogeneous second order delay differential equations with variable coeffcients. Group methods have been used to do this. The approach followed by us to ...
