    We considered the fourth order elliptic equation with non-constant coefficientswhere Lu: = a_(ij)(x}u_(ij) is a uniform elliptic operator.

    其次考虑了具非常系数的四阶椭圆型方程L~2u+g(x,u,Lu)+p(x)f(u)=0,其中Lu:=aij(x)u,ij是一致椭圆算子。

Elliptic operator

  • abstract: In the theory of partial differential equations, elliptic operators are differential operators that generalize the Laplace operator. They are defined by the condition that the coefficients of the highest-order derivatives be positive, which implies the key property that the principal symbol is invertible, or equivalently that there are no real characteristic directions.
