   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Cauchy problems for elliptic equations arise in applications in science and engineering. These problems often involve finding important information about an elliptical system from indirect or incomplete measurements. LÄS MER

3. 2. Regularization methods for solving Cauchy problems for elliptic and degenerate elliptic equations

   Sammanfattning : In this thesis, we study Cauchy problems for the elliptic and degenerate elliptic equations. These problems are ill-posed. We split the boundary of the domain into two parts. On one of them, say Γ0, we have available Cauchy data and on remaining part Γ1 we introduce unknown Robin data. LÄS MER
