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

    University dissertation from Linköping : Linköpings universitet

    Author : Jonas Lundgren; Linköpings universitet.; Linköpings universitet.; [2002]
    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

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

    University dissertation from Sundsvall : Mittuniversitetet

    Author : Abtin Daghighi; Mittuniversitetet.; [2012]
    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
