  6. 4. Reconstruction of stresses in plates by incomplete Cauchy data

    Author : Jonas Lundgren; Björn Gustafsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : We consider an ill-posed boundary value problem from classical plate theory for the biharmonic equation. The boundary conditions involve incomplete Cauchy data on one part of the boundary and an extra condition on the other part. READ MORE

  7. 5. The Maximum Principle for Cauchy-Riemann Functions and Hypocomplexity

    Author : Abtin Daghighi; Stefan Borell; Christer Kiselman; Egmont Porten; Juergen Leiterer; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hypocomplexity; hypoanalytic structure; CR functions; maximum principle; weak pseudoconcavity;

    Abstract : This licentiate thesis contains results on the maximum principle forCauchy–Riemann functions (CR functions) on weakly 1-concave CRmanifolds and hypocomplexity of locally integrable structures. Themaximum principle does not hold true in general for smooth CR functions,and basic counterexamples can be constructed in the presenceof strictly pseudoconvex points. READ MORE
