Published in 2019 at "Afrika Matematika"

DOI: 10.1007/s13370-019-00685-0

Abstract: We study an algorithm to compute minimum norm solution of ill-posed problems in Hilbert spaces and investigate its regularizing properties with discrepancy principle stopping rule. This algorithm results from straightly applying the LSQR method to… read more here.

DOI: 10.1007/s40314-023-02555-9

Abstract: The class of quasimonotone mappings are known to be more general and applicable than the classes of pseudomonotone and monotone mappings. However, only very few results can be found in the literature on quasimonotone variational… read more here.

DOI: 10.1016/j.ifacol.2020.12.1136

Abstract: This paper proposes a discrete-time, distributed algorithm for multi-agent networks to achieve the minimum l1-norm solution to a group of linear equations known to possess a family of solutions. We assume each agent in the… read more here.

Published in 2020 at "Journal of Mathematical Analysis and Applications"

DOI: 10.1016/j.jmaa.2020.124492

Abstract: Abstract In this paper we investigate continuous linear operators between Banach spaces which attain their minimum norms on the unit sphere. We characterize finite dimensionality of Banach spaces with the help of minimum norm attainment… read more here.

Published in 2024 at "Symmetry"

DOI: 10.3390/sym16070809

Abstract: Minimum norm problems consist of finding the distance of a closed subset of a normed space to the origin. Usually, the given closed subset is also asked to be convex, thus resulting in a convex… read more here.
