Dual gradient method for ill-posed problems using multiple repeated measurement data
Qinian Jin, Wei Wang
We consider determining -minimizing solutions of linear ill-posed problems , where is a bounded linear operator from a Banach space…
Dual gradient flow for solving linear ill-posed problems in Banach spaces
Qinian Jin, Wei Wang
We consider determining the -minimizing solution of ill-posed problem for a bounded linear operator from a Banach space to a Hilbert space , where…
Analysis of a Backward Euler-type Scheme for Maxwell's Equations in a Havriliak-Negami Dispersive Medium
Yubo Yang, Li-Lian Wang, Fanhai Zeng
For the Maxwell's equations in a Havriliak-Negami (H-N) dispersive medium, the associated energy dissipation law has not been settled at both continuous level and discrete level. I…
Tikhonov regularization with l^0-term complementing a convex penalty: l^1 convergence under sparsity constraints
Wei Wang, Shuai Lu, Bernd Hofmann +1
Measuring the error by an l^1-norm, we analyze under sparsity assumptions an l^0-regularization approach, where the penalty in the Tikhonov functional is complemented by a general…
An iteration regularizaion method with general convex penalty for nonlinear inverse problems in Banach spaces
Jing Wang, Wei Wang, Bo Han
In this paper, we discuss the construction, analysis and implementation of a novel iterative regularization scheme with general convex penalty term for nonlinear inverse problems i…
Elastic-net regularization for nonlinear electrical impedance tomography with a splitting approach
Jing Wang, Bo Han, Wei Wang
Image reconstruction of EIT mathematically is a typical nonlinear and severely ill-posed inverse problem. Appropriate priors or penalties are required to enable the reconstruction.…
