    Harmonic Function and Partial Di erential Equations
    (Addis Ababa University, 2019-07-05) Debebe, Wubshet; Biset, Tesfa (PhD)
    This paper is concerned with harmonic function and partial di erential equation. Harmonic functions are regarded as solutions of Laplace equation which have a number of properties that are essential in solving partial di erential equation.Poisson integral is applied to obtain useful inequalities for positive harmonic functions.
