  4. 4. Parabolic equations with low regularity

    Detta är en avhandling från Department of Mathematics, Lund University

    Författare :Magnus Fontes; Lunds universitet.; Lund University.; [1996]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics; Galerkin approximation.; low regularity; variational method; Hilbert transformation; fractional calculus; parabolic equations; quasilinear;

    Sammanfattning : Popular Abstract in Swedish Avhandlingen innehåller en ny metod att behandla ekvationer av den typ som styr t.ex. värmeledning och diffusion. Användning av ''halva derivator'' i tidsled möjliggör ett angreppssätt mycket likt den välkända Dirichlets princip inom elektrostatiken. LÄS MER
