以Dirac测度为源的拟线性退化抛物方程解的唯一性

The Uniqueness of Solution to a Quasilinear Degenerate Parabolic Equation with Dirac Measure

研究了以Dirac测度为源的拟线性退化抛物方程ut-Δum=δ(x),(x,t)∈Q的Cauchy问题解的唯一性,其中δ(x)是Dirac测度,m>1,Q=RN×(0,+∞).

The uniqueness of solution to the quasilinear degenerate parabolic equation ut-Δum=δ（x） ,（x,t） ∈Q was proved.where δ（x） was the Dirac measure centered at the origin,m1,Q=RN×（0,＋∞） .
