Differential Equations for Roaming Pseudospectra: Paths to Extremal Points and Boundary Tracking
Abstract. When studying the ε-pseudospectrum of a matrix, one is often interested in computing the extremal points having maximum real part or modulus. This is a crucial step, for...

Optimal Boundary Control of Convention-Reaction Transport Systems with Binary Control Functions
We investigate a new approach for solving boundary control problems for dynamical systems that are governed by transport equations, when the control function is restricted to binar...

Detection of Encrypted Tunnels Across Network Boundaries
— The use of covert application-layer tunnels to bypass security gateways has become quite popular in recent years. By encapsulating blocked or controlled protocols such as peert...

Finite element approximation for equations of magnetohydrodynamics
Abstract. We consider the equations of stationary incompressible magnetohydrodynamics posed in three dimensions, and treat the full coupled system of equations with inhomogeneous b...

Sufficient Second-Order Optimality Conditions for Semilinear Control Problems with Pointwise State Constraints
Second-order sufficient optimality conditions are established for the optimal control of semilinear elliptic and parabolic equations with pointwise constraints on the control and t...
