where ‖·‖Lr denotes the usual norm for L (Ω) with 1 ≤ r ≤ ∞, the functions yd, f ∈ L (Ω) are given, and the scalar parameters b, c, β ≥ 0 and ν, β ≥ 0 are known. Our model includes problems such as the simplified GinzburgLandau superconductivity equation as well as inverse problems where Lregularization is used to enhance sparsity of the control function u. For simplicity, the domain Ω ⊂ R is assumed to be a rectangle (0, L̃)× (0, L̂). The function φ : R → R is assumed to be of class C, with…

Convergence analysis of the Schwarz alternating method for unconstrained elliptic optimal control problems
Numerical results corroborate the theoretical results and show that with α decreasing to zero, the method will converge faster, and gives some exposition of this phenomenon.


Optimality Conditions and Error Analysis of Semilinear Elliptic Control Problems with L1 Cost Functional
Semilinear elliptic optimal control problems involving the $L^1$ norm of the control in the objective are considered. Necessary and sufficient second-order optimality conditions are derived. A priori

For solving the non-differentiable optimal control problem, a semismooth Newton method is proposed that can be stated and analyzed in function space and converges locally with a superlinear rate.
Optimal Control of Partial Differential Equations: Theory, Methods and Applications
Optimal control theory is concerned with finding control functions that minimize cost functions for systems described by differential equations. The methods have found widespread applications in
Newton Methods for the Optimal Control of Closed Quantum Spin Systems
An efficient and robust computational framework for solving closed quantum spin optimal-control and exact-controllability problems with control constraints is presented and existence and regularity of optimal controls are proved.
Analysis of the Parallel Schwarz Method for Growing Chains of Fixed-Sized Subdomains: Part I
It is proved numerically that the convergence of the Schwarz method in this case does not depend on the number of subdomains, even without coarse correction, by analyzing the Schwarz iteration matrices in Fourier space and evaluating corresponding norms in a simplified setting.

This paper analyzes these new methods for symmetric positive definite problems and shows their relation to other modern domain decomposition methods like the new Finite Element Tearing and Interconnect (FETI) variants.
On the Scalability of Classical One-Level Domain-Decomposition Methods
One-level domain-decomposition methods are in general not scalable, and coarse corrections are needed to obtain scalability. It has however recently been observed in applications in computational
