Coefficient Control of Variational Inequalities

Andreas Hehl, Denis Khimin, Ira Neitzel +3

Within this chapter, we discuss control in the coefficients of an obstacle problem. Utilizing tools from H-convergence, we show existence of optimal solutions. First order necessar…

Global-in-time solutions for quasilinear parabolic PDEs with mixed boundary conditions in the Bessel dual scale

Fabian Hoppe, Hannes Meinlschmidt, Ira Neitzel

We prove existence and uniqueness of global-in-time solutions in the $W_{D}^{- 1, p}$ - $W_{D}^{1, p}$ -setting for abstract quasilinear parabolic PDEs with nonsmooth data and mixed boundary…

Analysis of Four-Dimensional Variational Data Assimilation Problems in Low Regularity Spaces

Paula Castro, Juan Carlos De los Reyes, Ira Neitzel

We carry out a rigorous analysis of four-dimensional variational data assimilation ( $4 D$ -VAR) problems for linear and semilinear parabolic partial differential equations. Continuit…
