Summary[edit]
| Description |
An approximation of the negative indicator function of an ellipse in the plane (left), the derivative in the direction normal to the boundary (middle), and its Laplacian (right). In the limit, the right-most graph goes to the (negative) Laplacian of the indicator. Purely intuitively speaking, the right-most graph resembles an elliptic castle with a castle-wall on the inside and a moat in front of it; in the limit, the wall and moat become infinitely high and deep (and narrow). |
