一类具有内部退化的椭圆型方程

A Class Of Elliptic Equations with Interior Degeneration

Patrick Guidotti

摘要:

考虑一类受图像处理中非线性扩散问题启发的线性退化椭圆型方程。它的特点是扩散系数的内部退化。它表明,没有特别自然的,唯一的解释方程是可能的。这种现象反映在数值方案的行为,其分辨率和点类似的问题,可能会影响其非线性对应。

英文摘要:

A class of linear degenerate elliptic equations inspired by nonlinear diffusions of image processing is considered. It is characterized by an interior degeneration of the diffusion coefficient. It is shown that no particularly natural, unique interpretation of the equation is possible. This phenomenon is reflected in the behavior of numerical schemes for its resolution and points to similar issues that potentially affect its nonlinear counterpart.
