And we all know that the Laplacian operator is by far the most important differential operator in Mathematical Physics. |
|
Equation 1 implicitly assigns a unary weight to each level of the Laplacian pyramid. |
|
The state matrix of the equation is time-dependent and no longer a Laplacian matrix, and is neither symmetric nor diagonalizable. |
|
Unfortunately, their strategy only worked for the 3D Navier-Stokes equations when the Laplacian operator A in was replaced by another similar linear operator. |

The LaPlacian and gradient terms were solver with a 2nd order Gaussian integration technique. |
